Cold. Â Wet. Â Dark. Â Thereâs something slightly mad about the mountain biker who takes on a 24 hour race. Â How about winter in Kielder to tickle your fancy? Â Solo, pairs or quads. Â This competitive event will give you the chance to keep your cycling mo-joÂ going and challenge yourself in what can be some severely testing conditions. Â Bring supporters or bring your team mates and spend the weekend out on the course as you summon up the strength of mind and body to keep going.
