The 14th edition of the Ultra-Trail du Mont-Blanc (UTMB), the mountain ultra-marathon which takes place annually in the Alps, has found all the 150 solidarity race-bibs available for runners making donations taken up. The organizers guarantee one place in the race, up to a limit of 150 places, to any runner who donates €2,000 to one of the charities supported by the race. The runner can donate the money either directly or through a supporting donor, private or commercial. The donations must be given by May 31, at the latest. In order to enroll in the race, runners normally have to rely on a draw, which they bypass if they make this donation. As from the moment that the runner who enrolls through a donation is registered, he is subject to the same race regulations as the other runners.

The associations supported by the UTMB's solidarity race-bibs are the Chamonix section of the Rotary Club, Les Amis de Children's Home, Frères des Hommes, Le Rire Médecin, Association Liziba Suisse, Plan, Greffe de Vie, Association Chuma La Deedi's School, Soutien Orphelinat Pagala, and the French Foundation for Rare Diseases. The solidarity race-bibs have been chosen by runners of 22 different nationalities, with France in the lead, followed by the U.S., Germany, China and Japan.

Other than the solidarity race-bibs, each runner can choose on registration whether or not to make a donation to one of the associations supported by the UTMB. Runners have collected €24,000 in this way for the 2016 event, bringing the total for the charitable projects to €324,000.

The money that is being raised this year will be devoted to projects such as the creation of a school in Tipine, Nepal, the cleansing of around 15 natural springs and the construction of water reserves in the city of Bulape, in the Democratic Republic of Congo, donations to promote women's literacy in India, and more.
