The Greenway Challenge Half Marathon is a rural trail run held in pleasant surroundings organised by North Herts Road Runners. The modest field of around 200 runners are rewarded with some lovely cake after the race.
Most will struggle to get a pb on this course partly due to several styles, kissing gates and road crossings and some killer hills that will all slow you down. It is a circular route - watch out for the particularly difficult hill at around the 10 mile mark - ouch!
