Both use restored traditional paths in the Sobrarbe area and start and finish in Bolta\u00f1a&#8217;s Plaza Mayor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The choice should not be based on distance alone. The long-race page lists 23.06 kilometres and 1,450 metres of climbing; the short option is branded as a 10K, yet the route embedded on the official website shows 9.07 kilometres and 424 metres. They are very different challenges, although both demand genuine trail experience, controlled pacing and attention to required kit. This guide brings together schedules, routes, cut-offs, aid stations, registration and a practical race plan.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key facts for O Viento Rondador 2026<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Date:<\/strong> Saturday, 26 September 2026.<\/li>\n\n\n\n<li><strong>Venue:<\/strong> Plaza Mayor, Bolta\u00f1a, in the Sobrarbe district of Huesca.<\/li>\n\n\n\n<li><strong>23K Vuelta a Naba\u00edn:<\/strong> 8:30 am start; 23.06km and 1,450m of climbing on the dedicated race page; 5 hours 40 minutes to finish.<\/li>\n\n\n\n<li><strong>10K Camino a San Gil:<\/strong> 9:30 am start; published track of 9.07km and 424m of climbing; 2 hours 30 minutes to finish.<\/li>\n\n\n\n<li><strong>Bib collection:<\/strong> Friday 25 September, 6:00-8:45 pm; Saturday 26 September, 7:30-8:15 am for the 23K and 7:30-9:15 am for the short race.<\/li>\n\n\n\n<li><strong>Prices currently displayed:<\/strong> \u20ac38 for the 23K and \u20ac33 for the 10K; <a href=\"https:\/\/ovientorondador.wordpress.com\/inscripciones\/\">official registration<\/a> remains open in the third price band.<\/li>\n\n\n\n<li><strong>Insurance:<\/strong> the rules add \u20ac3 for a day licence for non-federated runners.<\/li>\n\n\n\n<li><strong>Organisers:<\/strong> Club de Monta\u00f1a Naba\u00edn and Bolta\u00f1a Town Council; the rules describe it as a non-official event open to federated and non-federated runners.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The organisers presented the renewed programme on 8 September. According to the <a href=\"https:\/\/cadenaser.com\/aragon\/2026\/09\/08\/la-carrera-o-viento-rondador-abre-una-nueva-etapa-con-nuevos-recorridos-y-novedades-radio-huesca\/\">report following that presentation<\/a>, the event has spent 12 years connecting trail running, the local landscape and community life in Bolta\u00f1a. The 2026 edition moves from its traditional May slot to September and adds restored paths not used by the previous courses.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What changes in the 13th edition<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is more than a minor course adjustment. Vuelta a Naba\u00edn now reaches the summit itself, at roughly 1,760 metres according to the official homepage, before descending through new links towards Moriello de San Pietro and San Fert\u00fas. The short route climbs to the San Gil hermitage along a path restored for the race. The supporting programme now runs from Friday evening until Sunday lunchtime.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Those recovered paths give O Viento Rondador an identity beyond a generic mountain race. For runners, the practical consequence is that previous editions are a less reliable benchmark this year. Download the 2026 track, attend Friday&#8217;s race briefing where possible and follow the course markings. The <a href=\"https:\/\/ovientorondador.wordpress.com\/wp-content\/uploads\/2026\/06\/reglamento-o-viento-rondador.pdf\">official rules<\/a> state that on-the-ground marking takes priority if it differs from the GPS track on race day.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Vuelta a Naba\u00edn 23K: a concentrated mountain half marathon<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/ovientorondador.wordpress.com\/carrera-23k\/\">23K race page<\/a> lists 23.06 kilometres, 1,450 metres of climbing and five aid stations. The route leaves Bolta\u00f1a for Ascaso, climbs Naba\u00edn, follows the shelves facing Yeba and descends through Moriello de San Pietro and the San Fert\u00fas path before returning to the square.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dividing elevation gain by distance gives approximately 63 metres of climbing per kilometre. That is only a density measure, not the average gradient or a description of each section, but it exposes the main planning mistake: treating this like a road half marathon. Finish time will depend on terrain, the ability to hike steep gradients efficiently, descending skill and fatigue management rather than the kilometre pace shown on a watch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Naba\u00edn summit arrives near halfway and creates a crucial tactical decision. Reaching it above a sustainable effort can make the descent the most expensive part of the day. Leave breathing room on the first climb, alternate running and purposeful hiking before the slope forces the decision, and protect the quadriceps for the long descent. A runner who has not practised uneven descents cannot make up for that by attacking the climb.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Camino a San Gil: why the \u201c10K\u201d is not a road 10K<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/ovientorondador.wordpress.com\/carrera-10k\/\">short-course page<\/a> contains a useful planning discrepancy: the race is called a 10K, but its embedded profile states 9.07 kilometres and 424 metres of climbing. The homepage rounds that to 10 kilometres and 420 metres, while the rules say 10K and 428 metres. This may reflect rounding or different route versions; until the organiser updates the figures, the specific track is the most precise reference available.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whatever the final measurement, runners should not project a road 10K time onto this race. Around 424 metres of climbing in just over nine kilometres, restored paths and terrain described as technical by the organiser completely change the effort. A fast road runner with limited descending experience may lose more time and control going downhill than uphill.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The short race is open to athletes born in 2012 or earlier. Minors must provide authorisation from a parent or guardian at bib collection. It is the more accessible option, but short does not mean easy: there is an approximate cut-off at kilometre seven after 1 hour 30 minutes and the finish closes after 2 hours 30 minutes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to choose between the 23K and 10K<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Choose the 23K<\/strong> if you have completed several-hour mountain runs, tolerate more than 1,000 metres of climbing, can descend under control after a long ascent and know how to fuel while moving.<\/li>\n\n\n\n<li><strong>Choose the 10K<\/strong> if you want a shorter experience, your recent preparation suits efforts of up to two and a half hours, or you are still building mountain autonomy.<\/li>\n\n\n\n<li><strong>Do not rely only on a road 10K or half-marathon PB.<\/strong> Elevation, surface and technical demand break the equivalence. Review recent time on trails, not weekly kilometres alone.<\/li>\n\n\n\n<li><strong>Observe the age rules.<\/strong> The 23K requires runners to be 18 on race day; the short race accepts those born in 2012 or earlier, with authorisation where required.<\/li>\n\n\n\n<li><strong>When uncertain, assess descending skill.<\/strong> Finishing safely matters more than choosing a particular distance. The ability to descend when tired is as important as uphill strength.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A useful check is to review the past six weeks: have you completed at least two trail outings reasonably close to the expected duration and elevation, without pain and with normal recovery? This is not an official requirement or a guarantee, but it is more honest than one isolated flat-road performance. With fewer than three weeks remaining, there is no time to build a major adaptation safely; there is time to refine kit, nutrition and pacing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Cut-offs and aid stations: how to use the clock<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The 23K has five liquid and solid aid points: Liaso at km 5, Ascaso at km 8, Naba\u00edn at km 11, the Naba\u00edn descent at km 15 and the San Fert\u00fas path at km 17. Cut-offs are Ascaso after 1:30, Pista de Morillo after 3:40 and the finish after 5:40. The short race announces two aid stations, an approximate km 7 cut-off after 1:30 and a 2:30 finish limit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Those limits should not become an even-pace schedule. A steep kilometre can take several times longer than a favourable one. Carry three visible references instead: margin at the first cut-off, a planned time at the high point and a final reserve. If the margin disappears early, a sudden acceleration down technical terrain may add risk without solving the problem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aid stations will not provide cups. Every runner needs a cup or compatible container. Although the long race has five stations, the mandatory one litre at the start should not be emptied mechanically before the first control. Intake depends on duration, temperature, sweat rate and individual tolerance. Use a plan tested in training and adjust sensibly rather than forcing large volumes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Required kit and mountain safety<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The rules require suitable footwear and clothing, a visible bib, charged mobile phone, and a cup or container. The 23K also requires at least one litre of fluid. A waterproof jacket with hood and long sleeves may become mandatory depending on the forecast. Kit can be checked before the start, and the organiser will announce any amended or expanded list.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Download the track for offline use, while remembering that course markings remain the primary reference.<\/li>\n\n\n\n<li>Protect the phone and carry enough battery; save the incident number that the organiser will provide.<\/li>\n\n\n\n<li>Test shoes, socks, pack or belt and drinking vessel on a real outing. Race day is not the moment to debut a hydration system.<\/li>\n\n\n\n<li>Carry the recommended emergency blanket and whistle even if they do not, for now, appear on the mandatory list.<\/li>\n\n\n\n<li>Check final race communications and <a href=\"https:\/\/www.aemet.es\/es\/eltiempo\/prediccion\/montana?p=arn1&amp;w=\">AEMET&#8217;s mountain forecast for the Aragonese Pyrenees<\/a> once the race enters its four-day window. On 9 September it is too early for a reliable 26 September forecast.<\/li>\n\n\n\n<li>If you withdraw, do so at a control and hand in the bib. Outside a control, inform the race incident number as soon as possible; <a href=\"https:\/\/112aragon.aragon.es\/index.php\/que-es-112\">Arag\u00f3n&#8217;s 112 service<\/a> is for emergencies.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The rules also require runners to help another participant in need, prohibit shortcuts and require waste to be carried to the finish. These are sporting, environmental and safety obligations. Every control is mandatory; missing one results in disqualification.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What to train in the final two weeks<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">At this stage, the goal is no longer to prove fitness in one heroic workout. The final long hilly outing should leave enough time to recover. After that, keep small doses of climbing and familiar technical descent, maintain normal frequency and reduce volume gradually. Pain that alters gait or worsens while running deserves rest and assessment, not another test session.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>For the 23K:<\/strong> one short, controlled hill session and one easy outing with a familiar technical descent, without creating lasting soreness.<\/li>\n\n\n\n<li><strong>For the short race:<\/strong> pace changes on rolling ground and practice hiking purposefully on a steep slope.<\/li>\n\n\n\n<li><strong>For both:<\/strong> rehearse opening containers, reaching food without stopping and checking the track with sweaty hands.<\/li>\n\n\n\n<li><strong>During race week:<\/strong> clearly reduce duration, keep a few lively minutes if they are already part of your routine, and prioritise sleep, regularity and familiar food.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This is not a universal schedule. Adjust it to your normal training. Adding poles, a new technique, a heavy eccentric workout or different shoes now may create more fatigue than adaptation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Race plan: climb with margin, descend with attention<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The atmosphere in Plaza Mayor may make the opening pace feel effortless. In the 23K, the first minutes should be deliberately controlled. Hiking early on steep slopes is not surrender; it may be the most efficient way to protect heart rate and muscle. Near Naba\u00edn, check food, fluid and concentration before beginning the descent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The shorter duration can encourage an aggressive 10K start. Save maximum effort until you have read the terrain and completed the main climb. On both routes, pass only where there is space, communicate calmly and do not force the issue on a narrow path.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kilometre pace will offer little guidance on technical sections. Breathing effort, foot stability and cumulative time relative to controls are more useful. The watch helps; the terrain decides.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The full weekend programme in Bolta\u00f1a<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.clubnabain.es\/2026\/09\/programa-trail-o-viento-rondador-2026.html\">programme published by Club de Monta\u00f1a Naba\u00edn<\/a> begins on Friday 25 September in Plaza Mayor. A technical briefing starts at 6:30 pm, followed at 7:15 pm by a discussion about the origins of the restored paths. On Saturday, after the adult races, the schedule includes lunch at 1:30 pm, prizes at 3:30 pm, a children&#8217;s workshop at 4:45 pm, a children&#8217;s race through the old town at 5:30 pm, hot chocolate and music.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sunday 27 September completes the weekend with a hiking outing at 7:30 am, a guided trail run around Bolta\u00f1a at 9:15 am, an old-town walk at 9:30 am and an aperitif at 12:30 pm. Several activities depend on participation numbers, so confirm arrangements with the organiser.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Registration, categories and details to confirm<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The website currently displays third-band prices of \u20ac38 for the 23K and \u20ac33 for the 10K. Entry includes a technical shirt, aid stations, race assistance, showers, post-race food and Saturday&#8217;s hot chocolate. The page does not show an unambiguous final date for this band, so runners should check the form and confirm availability before arranging travel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both distances have overall, veteran 45+, veteran B 55+ and local Sobrarbe categories. The short race adds an under-18 category. Awards are not cumulative. The long race also recognises the first runner to reach Naba\u00edn, a prize that should not distort the plan of anyone not specifically racing for it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before travelling to Bolta\u00f1a, verify four items in the same official source: final route version, definitive kit list, registration status and any schedule changes. The organiser can amend the rules and will communicate changes on its website or by circular.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions about O Viento Rondador 2026<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">When is the race and when does each distance start?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Saturday, 26 September. The 23K starts at 8:30 am and the 10K at 9:30 am from Plaza Mayor in Bolta\u00f1a.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is the short route exactly 10 kilometres?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The event calls it a 10K, but the dedicated official page shows a 9.07km track with 424m of climbing. The homepage and rules use rounded or slightly different figures. Follow the latest track and organiser instructions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How much fluid is mandatory?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The rules require at least one litre for the 23K and recommend half a litre for the short race. A cup or container is mandatory in both because aid stations will not provide cups.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can non-federated runners enter?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. This is a non-official event open to federated and non-federated runners. The latter must take the organiser&#8217;s day insurance for an additional \u20ac3.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the best way to choose a distance?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Compare recent experience by duration, elevation and terrain. The 23K demands several hours of autonomy and the ability to descend while tired; the short course reduces total time but retains elevation density and terrain unlike a road 10K.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Editorial note: distances, elevation, prices, schedules and rules checked on 9 September 2026.
