Notable runners
Route
The OCC begins in Orsières in Switzerland and finishes in Chamonix, France. The route offers up breathtaking views of the valley and the peaks of the eastern flanks of Mont Blanc.
This year (there are often tiny changes each edition) it covers 57km and features 3,498 metres of climbing.
Beginning with the unique Swiss landscapes, the route heads to Champex-Lac and Trient. Runners then cross the Franco-Swiss border by the Balme pass.
The final climb heads up to La Flégère and then it’s downhill all the way to the centre of Chamonix.
Analysis
We’re in for an absolute treat in the first of the week’s big three races.
Rémi Bonnet tops the UTMB Index with a whopping score of 948 which sees him lead the way worldwide for the men, just ahead of the GOAT Kilian Jornet and Kenya’s Patrick Kipngeno.
Bonnet is back at OCC for the first time in three years and we also have a Swiss star at the top of the women’s rankings for this race in the shape of Judith Wyder (792), who has returned to winning ways in great style in the Golden Trail World Series this season by landing the 42 km Marathon du Mont-Blanc.
She won’t have things all her own way though, as Dani Moreno (USA / 786) was third in the 2022 OCC, while another US star in Allie McLaughlin (780) returns for the third consecutive year with her sights set on the podium.
Among the European contingent, French athlete Clémentine Geoffray (791), first in the 2023 MCC, Spain’s Sara Alonso (775), and Italian Elisa Desco (760) are all genuine contenders.
And other big names are China’s Miao Yao (785), third in the 2023 OCC, and New Zealand’s Caitlin Fielder (775), who narrowly missed the podium in the 2023 race.
Back to the men’s and Bonnet’s big rival had looked to be Britain’s Jon Albon, the winner of this race in 2021 and CCC 12 months ago and who was dropping down markedly in distance after racing over 100 miles at Western States recently.
But he revealed on the eve of the race that he wouldn’t be running, saying on Instagram: “After Western I’ve had some niggles… I realised UTMB was not a realistic option, and decided to drop down in distance. I was hoping to be ready just in time, but unfortunately the body isn’t quite ready.”
There’s another Brit in Robbie Simpson (906), who has been in fine form in 2024, including a 50km win at the 2024 Eiger Ultra-Trail by UTMB.
American Eli Hemming (914) landed the 2024 HOKA Canyons Endurance Runs by UTMB while another notable name is Italian Francesco Puppi (917), who finished second in the 2023 OCC.
French hopes appear to rest on Sylvain Cachard (911) and Benjamin Roubiol (902).
