RIDER FIT
Built for hours in the saddle — your distance
Significant climbing rewards low-watt grinding
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
2816 km is not a race — it's an expedition. Pacing is decided by hours, not km splits, and sleep strategy matters more than power.
TIRE INTEL
Variable wet conditions — favour grip.
WEATHER PLAYBOOK
Bozeman, Montana in mid-summer (July): expect mild conditions — pack for variable weather. Always check 7-day forecast race week and pack a packable shell.
PACING PLAYBOOK
Resist the urge to push. Your race starts in 48 hours, not at km 0.
Eat early, eat often. Sleep matters more than watts now.
Mental low point. Stick to the plan. Most riders bonk here mentally before physically.
Save matches. The finish line will reveal itself when you stop chasing it.
WHAT TO FEAR

- [!02]Late-race climbs after the legs are gone
- [!03]Mental low point on the long, lonely middle section
- [!04]Resupply gaps — carry more food than you think
