The Harp Hilly Hundred Reliability Trial is a the first event in the Chiltern Classics series. Recognised as one of the harder reliability trials in the area because of the unrelenting terrain through the Chilterns, it was originally run over a distance of 100 miles but is now approximately 100 kms, with a shorter option of 50 kms for those who don’t feel they are fit enough for the full distance.

The ride starts in Kings Langley, Herts, and follows a challenging route through the Chilterns via Chesham, Berkhampstead, Whipsnade, Ivinghoe & Tring. It then returns through Ivinghoe and Berkhampstead to finish back in Kings Langley. Major ascents on the route, which climbs 1315m, include the climbs of Bison Hill near Whipsnade, Aston Hill just outside Tring and Ivinghoe Hill past Ivinghoe Beacon.

Riders can choose one of three time bands to complete the 100km distance. Average speeds are 18.5mph, 15.5mph or 13mph depending on the time selected to complete the ride.  

The event will take place on 24th January 2010 with the HQ located at Nash Mills Recreation Centre, Red Lion Lane, Kings Langley, HP3 9TE. Entry fees  are £10 for the full 100km and £5 for the 50km rides.

New for 2010, riders can enter the Harp Hilly Hundred Reliabilty Trial online at www.HarpHillyHundred.org.uk or, as ever, on the day.
