Kielder Calling, powered by Purple Mountain and supported by British Cycling, is back for its second instalment this summer.

After a successful first year, the race is once again set in the heart of Kielder Forest, Northumberland over the bank holiday weekend, May 28-29.

The seven-mile course will feature fast-flowing, all-weather single track, mixed with forest fire road to make for a leg-burning route.

The Kielder Calling will see the three-hour junior/novice race and six-hour enduro held on the Saturday, building up to the main event of the 12-hour race on the Sunday.

Categories cover solo, pair and team entries across all races. The first 50 entrants will receive a pair of MTB Extreme Sox worth £8.

With Osprey and On One supporting the event, podium finishers can expect to receive a great selections of prizes. There will be an event goodie bag and medal for every competitor.

Alongside the weekend’s race action there will be a full event arena with demo bikes and trade stands with all the latest kit and tech support. On-site catering and camping facilities are available all weekend.
