Description
Note - this is a one-way route designed to allow travel to/from the event by train - see details later. You can use E-brevet or answer info questions at the intermediate controls.
Start by cycling into the foothills of the Chilterns with a climb up the delightful in nature if not in name Bottom Lane. A rolling route drops you down into the valley at Kings Langley, then climbs again to Bedmond, before descending through wooded countryside. A short section on a gravel track - no problem for road bikes - leads into the private and virtually motor traffic free Gorhambury Drive, past the ancient manor house, with views of St Albans Abbey in the distance. There are food, drink and toilet facilities in Verulanium Park or at the nearby Retail Park. You leave the city via the Greenway and head south to Colney Hatch and Welham Green. From there take the lanes up into an attractive part of Hertfordshire, past the zoo before dropping down to Broxbourne in the Lee Valley to finish at the Mill Retreat cafe.
You can get to Watford on the Metropolitan line 4 trains per hour, or to Watford Junction/Watford High Street 2 fast trains per hour LNWR and 2 slow Overground trains per hour with a 2km ride to the start route will be provided. The finish is close to Broxbourne station 4 x Greater Anglia trains per hour to Liverpool Street. No trains require bike reservations and you can use Oyster/PAYG to buy tickets less than £10 - an over 60 or Freedom pass will reduce the trip to Watford to zero if you take the Met Line or Overground. NB Currently there are no scheduled engineering works or other disruptions for this date - if something is announced the event may be rescheduled.
If you would prefer a flatter 50km event with a lower minimum speed try the Broxfield 50 instead.
Why Watbourne.... think Bakerloo...
