Gwdir Forest course closely resembles that used for the 2013 world championships
Entries are being taken for a new race called the Snowdonia Endurance Trail, due to be staged on September 29, 2018.
The event will take place on a 5k loop covering much of the same trails around the picturesque Gwydir Forest used in the 2013 IAU Trail World Championships. Runners will run as many laps as possible over one hours, two hours or three hours.
The cost for participants will include entry to the Snowdoniafest weekend, of which the race is part. The festival is a full day of music, sports and film.
