THE world's biggest 24-hour mountain bike festival -- Saab Salomon Mountain Mayhem -- comes to Eastnor Castle Deer Park this weekend.

There is free entry for visitors to watch the three days of non-stop action, starting today, as well as visiting one of the many manufacturer displays at the venue.

In addition to the 24-hour endurance event, there will be a specially designed 'mini-mayhem' course for the kids complete with rumble strips, skinnies and limbo bars.

Skills coaching will be available from the experts at CycleActive for all young riders and each participant will receive a medal plus certificate in addition to being entered into a free prize draw to win three children's Giant mountain bikes.

Saab Salomon Mountain Mayhem also includes jugglers, stilt-walkers, face pain-ters, climbing wall, bungee jump and the bouncy castle.
