A good hour round Swinley Forest, Bracknell with three other RB members, had my best over the handlebars 'off' in years, got seperated from the others on a twisting technical downhill section, and got totally lost on my way back to the entrance.
All in have no real idea what my mileage was, probably around 12-15 miles, got totally soaked and caked in mud. Loved it. (apart from all of us suffering various technical issues with all the sandy mud).
