Mont-Blanc, live.

Around Mont Blanc, across three countries

The complete circuit from Chamonix: 174 kilometres and 10,000 metres of ascent through France, Italy and Switzerland.

UTMB leaves Chamonix for a full journey around the Mont Blanc massif. The 174-kilometre course crosses France, Italy and Switzerland, accumulating 10,000 metres of climbing before returning to the same town. Long nights, major passes and changing valleys make the runner’s place on the route more useful than a single split time.

On Livebib, the circuit becomes one continuous live story. Followers see the runner move across the map, the ascent already completed and the checkpoints still ahead, with updated arrival estimates as pace changes. One link follows the entire route back to Chamonix.
