RIDER FIT
Built for hours in the saddle — your distance
Limited use for pure climbers
Ultra format = guided adventure with timing chips
Self-supported format suits bikepacking instincts
Technical terrain rewards bike-handling
Single-day pace suits crit-style riders less here
Technical terrain rewards the bike-handler. Slow corners, line choice, and tire pressure will shape your race more than threshold watts.
TIRE INTEL
Mixed gravel with no extreme demands — go for rolling speed.
WEATHER PLAYBOOK
Rocha in spring (October): expect mild conditions — pack for variable weather. Always check 7-day forecast race week and pack a packable shell.
PACING PLAYBOOK
Sit in. Let the start sort itself out. Pace by feel, not by rivals.
Where the field shatters. Stick to your power numbers, not the surge.
Save one match. The last 20% is where placement is decided.
