Loop de loop

Caldecott, 40 km. Traffic averse, I look for a more efficient way to train, one with less time and less traffic. So I go around in circles, with one loop six km long. As I head up one of the steepest hills in the country, someone shouts "100%!" then goes "oh!" A car comes up, I squeeze my brake, my rear tyre skids.

I go downhill safely. Nice, going round in circles can clock some distance.
