Hopefully I'll get this in before the forum goes down.
For Sunday, how about the Box Hill loop (or part thereof). Easy flowing trails, there is scope for a 3-4 hour ride if people want to carry on but I will need to head back early so will just be doing 2-3hrs. Starting from East Croydon at 10.00 or pick-up from Action Bikes in Wallington at 10.30am.
Also, the cyclo cross season is starting soon, so if anybody's thinking of dusting off their CX bike, this is the opportunity. The trails are mostly non-technical bridleway and a perfect introduction (or refresher) to off-road CX bike handling. Bear in mind though, the pace is easy (not training pace).
