Castel Grumello Walk

In 2025, the Castel Grumello Walk renewed the running event in Montagna in Valtellina, with the usual route through the mule tracks and villages above Sondrio. Participants tackled the climbs of "Runsc" and "Risc dei Mort", crossed the historic center with the fifteenth-century church of San Giorgio, and reached the evocative ruins of Castel Grumello.

Organized by ASD Pentacom as part of the Retici Balzi circuit, the event confirmed its character as a race immersed in the history and landscape of Valtellina, appreciated by local runners.
