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
Smoother surfaces let raw speed talk
Single-day pace suits crit-style riders less here
Distance like this rewards patience. The riders who win the last 30% are the ones who saved matches in the first 60%.
TIRE INTEL
Sandy sections benefit from lower pressure and width.
WEATHER PLAYBOOK
Graaff-Reinet in autumn (May): 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.
WHAT TO FEAR
- [!01]Resupply gaps — carry more food than you think
