Thames Trot

This popular 50-miler (not an oxymoron, actually) celebrates its 10th anniversary this year, with more than 400 runners expected to turn up to make their way along the banks of the Thames, taking in the constantly varied scenery between Oxford and the finish, at Henley. Twitchers among you may want to sign up for the chance to see the Red Kites that often glide about overhead in silent support. Oxfordshire, February 3, gobeyondultra.co.uk
