03
Sector 3 — The Finishing Stretch130 km

Save one match. The last 20% is where placement is decided.

WHAT TO FEAR

  • [!01]Pacing mistakes — most issues here are self-inflicted

▌ INCOMING TRANSMISSION

Forest gravel rewards bike-handling. The roots and shadows at Gravel Tro Breizh are where the field shatters.

▌ INCOMING TRANSMISSION

European gravel has a different rhythm — the long lunch stops, the espresso at km 60, the post-race beer that lasts hours. Gravel Tro Breizh captures that perfectly.
