Course and altitude: how to tackle the challenge
The La Paz Marathon route passes through several iconic areas of the Bolivian capital. The main race begins at Plaza San Francisco and descends through the valley towards the southern district, passing neighbourhoods such as Sopocachi and Miraflores. After crossing the Choqueyapu and Orkojahuira rivers, the route climbs back towards the historic centre.
The lowest point of the course sits around 3,210 metres above sea level, while the highest section reaches approximately 3,948 metres. This elevation range, combined with the thin air at altitude, places significant stress on the cardiovascular system and requires careful pacing throughout the race.
For many athletes, racing close to 4,000 metres can reduce performance significantly. Research suggests that aerobic capacity may drop between 10% and 20% for every 1,000 metres gained above 3,000 metres. Because of this, adjusting your pace, staying well hydrated and listening to your body are essential strategies on race day.
Registration and logistics
Registration is completed through Webscorer and costs 150 bolivianos. Places are limited, so registering early is recommended.
- Bib number with electronic timing chip.
- Official race T-shirt and commemorative cap.

Runner kits will be distributed at the race expo on 6–7 March between 9:00 a.m. and 7:00 p.m. Participants must bring proof of payment, identification and their medical certificate. If you are travelling internationally, keep in mind that the week before the race coincides with La Paz Carnival, so booking accommodation well in advance is highly recommended.
How to train for running at altitude
The altitude of La Paz requires a slightly different training approach. Consider the following tips:
- Arrive early: ideally reach La Paz at least 10 days before the race to allow your body to acclimatise.
- Adjust your pace: expect to run 10–20% slower than your sea-level pace.
- Hydration and nutrition: drink more fluids than usual and prioritise foods rich in carbohydrates and iron.
- Altitude training: if possible, combine altitude sessions with training at lower elevations.
- Listen to your body: symptoms such as headache, dizziness or extreme fatigue may indicate altitude sickness.
