Marathon des Sables runs a race tracking website to follow competitions. They do so by tracking the geolocation through ‘spot’ tags – click here to follow live.
The tracking devices will allow the race organiser to ensure no competitors get lost on the course.
Marathon des Sables Race Route
The exact route of this year’s race is unknown, but the distance – 252km – is known, and was split up into six stages over seven days as follows last year:
Stage 1 – 31.1km
Stage 2 – 40.8km
Stage 3 – 85.3km (two days)
Stage 4 – 43.1km
Stage 5 – 31.4km
Stage 6 – 21.1km
In addition to the distance, competitors must also combat the rough Saharan terrain, plenty of elevation, debilitating heat as well as carrying their supplies.
The course will be marked every 500m (dependent on the terrain) and each runner will be given a detailed book of the course.
Facts, Tips & FAQ
With the length of the course, the terrain, and the heat, runners will need to take all advice on board before committing in the Marathon des Sables.
Runners will need to bring, and carry, their entire food intake – between 21,000-28,000 calories for the seven days. Freeze-dried food is the recommended choice in an effort to reduce the amount of weight carried on course.
Proteins, fats and carbohydrates are the most important food groups. Water will be provided – with 120,000 litres consumed during the event – at the departure point, check points and arrival on each day.
The course is the equivalent of five and a half regular marathons while you carry equipment on your back – walking parts of the course is completely acceptable.
Mental preparation is as important as physical preparation for the event, the challenge to complete the course is tough and can be mentally draining.
With the temperature in the Sahara peaking at 50 degrees Celsius, headwear is a must. Wildlife on the course, including snakes, are rarely seen. However, runners are advised to check their kit thoroughly prior to embarking each day.
Marathon des Sables puts on Bivouacs – eight-man tents with groundsheets. These are allocated prior to the races and runners must choose their tent from within the space reserved for their registration country.
