Backyard Ultra Montgrí
Backyard Ultra Montgrí is a charity race held every summer in Torroella de Montgrí (Girona), benefiting Fundació Oncolliga Girona — an organisation that supports cancer patients and their families.
Format and circuit
Start at 21:00 from the Pavelló Municipal in Torroella de Montgrí. The 6.706 km loop with 90 metres of elevation gain follows trails around the Montgrí massif. With gentle elevation, it’s a fast circuit that leaves more rest time between loops — but the night start and June heat balance out the lower technical demands.
Solidarity and trail
What makes this backyard special is its charitable spirit. All proceeds from registrations go directly to Oncolliga Girona. Running hour after hour with that purpose adds extra motivation that many participants highlight.
The night
Starting at 21:00 means the first 8-9 hours are run in the dark. June nights on the Costa Brava are short and mild, but the darkness adds a mental component to the challenge. Sunrise around 6:00 is typically a mood-turning point for runners still in the race. Plan your fueling strategy with our nutrition calculator to stay on top of your energy needs loop after loop.
Race record
The current record stands at 41 loops (274.9 km in 41 hours), set by José Carlos Alcázar García.
Torroella de Montgrí and the Costa Brava
Torroella de Montgrí is a village with a medieval castle, just a few kilometres from L’Estartit and the Illes Medes — one of the best marine reserves in the Mediterranean. Ideal for combining the race with a few days on the Costa Brava.
