I was thinking of visiting the Olympic test event on mtb, aiming for the Headley area. It's a bit early though, aiming to get there for around 10 would mean leaving Wallington around 8-8.30. The race goes through twice around 10.30 to 11.30.
Hopefully, the crowds will be at Box Hill side of the circuit. but bring a bike lock just in case we need to leave the bikes against a tree for a half hour or so.

from the organisers website:
Spectators can cycle to any part of the race route that is open to traffic but cannot cycle on the course during road closures at any time. Given likely crowd numbers along certain areas of the route, the use of a bicycle may be impractical and should be considered carefully. Restrictions will be in place around the managed spectator areas.
