Competitive trail runners will be out in force at Bishop's Stortford on Sunday (October 29) for the UK Trail Running Championships, incorporated into the Stort 30.
Runners will take in 29 miles of trail up along the bank of the river Stort and back, plus a fraction on road around the start and finish.
Last year Sophie Carter established a women's course record of 3:39:15, while Mark Innocenti took the men's prize in a time of 3:16:52.
Both are back this year to face tough opposition. GB 100k runner Craig Holgate returns seeking his fourth win here, having set the course record in 2015. Also expected to do well are 72-minute half runner Josh Cox and 2:31 marathoner Phil Martin.
Gemma Carter will be looking to push her namesake Sophie closer than the 10-minute margin from last year when she was second. Kathryn Chapman, the winner five years ago, returns.
The course is flat, and organisers reported dry underfoot conditions midweek.
