This is easily the best Chiltern Collection I have ever seen assembled in to one event! This really is a Tour de Chilterns ,,,,, here are some highlights:
Ascents: Speen, Haw Lane (Bledlow Ridge) Bullock's Farm Lane, Dudley Lane, Pishill, Chinnor Hill, Woodway, Kop Hill, Longdown Hill, Wendover Woods, Hastoe, Toms Hill, Dunstable Downs, Graeme's Dyke (Berkhamsted), Eskdale Avenue (Chesham)
Descents: Small Dean Lane, Foxboro Hill, Fingest lane, Wardrobes, Whiteleaf, The Crong, Ivinghoe Beacon, Bison Hill, New Road (Berkhamsted)
There are others, such as Bottrells Lane and Magpie Lane for example, but the above are just selected highlights. In fact, the route passes the starts of Aston Hill and Kingston Hill too, so you could choose to, gratuitously, climb one and descend the other without adding much distance to the ride as a bonus!
Cracking route, a landmark event packed with landmarks!
