The map below is venue geography unless an official course trace is explicitly linked. Do not use the connecting line as a spectator route.
03 · Failure-proofing
Pre-agree the reunion
Screenshots, a fixed place, and a time threshold work when tracking, batteries, or cell networks fail.
It's a point-to-point-ish course, so spectating means picking one or two spots and committing.
Key points on course
- Start — 51.477, 0.001
- Finish — 51.503, -0.140
- Expo — 51.508, 0.030
Phones die and cell networks jam near big finish lines, so agree on a meeting point before the start. That one habit saves the day every time.
