Yes, we know it’s out of season, but we are running our 2021 Reliability on Sunday 5th September 2021.
A chance to get in a decent ride with a well planned route, catering and company.
Please note the following changes:
- There is a route change on the 50K caused by emergency roadworks – get a new route sheet and a new gpx (registered rides will get an email).
- To ensure we keep within allowed numbers, you can still decide on the day whether to do the 100 or the 50, but if you decide to do the 50, you cannot sign on or enter the hall until 09:20. 100 riders should vacate the hall by 09:25
- There is entry on the day, some places for the 100 and some for the 50
In normal times, one of the multi-club Chiltern Classic Series rides, the Willesden CC Reliability Rides offer some of the best cycling in the Chilterns, with free refreshments at Ride HQ and certificates to in-time finishers. There are 50km and 100km rides, starting from Chalfont St Peter.
For those who have ridden before, it’s an all new 50Km route and a 100Km route that has been modified while keeping the signature climbs of Kop Hill, Bledlow Ridge, Smalldean Lane and Quarry Hill
What is a Reliability Ride?
Traditionally Reliability Rides provided late winter (Jan-Mar) training rides where the object is to provide base fitness in preparation for the more demanding race training that will follow when the weather improves. However they are excellent events for both Audaxers and Sportive riders of every standard. Our 50km event is suitable for leisure riders. Time goals are set for the rides that entrants aim to better. The rides are not races, you are riding on the road.
There are two distances:
- A 50Km ride with 530 meters climbing. Setting off at 09:45, target time 2 hours 30 minutes which is 20 kph (12 mph)
- A 100Km ride with 1120 meters climbing. Setting off at 09:30 ,there are four targets
- Average speed 30kph (18 mph) within 3 hours 30 minutes
- Average speed 23kph (14 mph) within 4 hours 30 minutes
- Average speed 19kph (12 mph) within 5 hours 30 minutes
- Average speed 17kph (10mph) within 6 hours
Choose your ride and target on the day.
At any time of year many roads in the Chilterns can be in poor condition with bad surfaces and potholes
Both rides take in sections in the lanes, although these are uphill or on the flat: descents are on reasonable or good roads (one short exception, which is flagged).The lanes may have debris, rotting leaves and standing water.
The 100KM route takes in Kop Hill and Smalldean Lane, two of the most challenging climbs in the Chilterns.
Both distances largely avoid A roads.
There are no organised refreshments or sag wagons en-route. You should be self-sufficient. However, for the 100Km there are cafes and toilets in Great Missenden and Marlow and service stations with shops at 36Km and 55Km. For the 50Km, Chipperfield has cafes.
GPS files and turn-by-turn instructions are available (see below). These will be supplemented with arrows at turning points. Beware that members of the public may remove them and in some places the only possible attachment points are not easy to spot!
GPX track files and route sheets
There are minor changes made and entrants will be emailed definitive GPXs and instructions shortly before the event (by Friday, 3rd September).
GPX files for both events (reduced to 3000 points or less).
If a standard GPX won’t work for you, use these links to Ride with GPS. You may need to check how many points your device can handle if you export from Ride with GPS.
There are risks from bad weather conditions and the 100Km route is tough so…
- Minimum age 12
- Under 14s can only ride the 50Km event, with a responsible adult.
- Under 16s can ride either distance, with a responsible adult.
- 16 and 17 year olds can ride either distance unaccompanied.
In every case a Parental Consent Form must be filled in by a parent or legal guardian and brought to the event.

Ride HQ and getting there
Chalfont St Peter Community Centre
Chalfont St. Peter,
Bucks SL9 9QX
Please don’t use the centre’s parking: that will be used by other events during the day. There is free parking on Sundays at the large Church Lane car park, off Church Lane, SL9 9RS. See the map. Take a path at the end of Cordon’s Close to reach the HQ.
HQ will be open to 100km riders from 08:45 to 09:25 and for 50km riders from 09:20. The HQ will close at approximately 4pm.
You walk in by the back of the Centre into the main hall. The normal main entrance is closed.
Please bring a mask.
By public transport from London
Marylebone to Gerrards Cross on Chiltern is the best bet, depending of course on no engineering work on the Chiltern Line that weekend – so please double-check. You can get an Advance Single by booking ahead of time and in previous years it has been for as little as £3. Allow 15 minutes from the train to the starting line.
Uxbridge, Rickmansworth, Chorleywood are Underground alternatives. From Uxbridge it’s main roads, but they are pretty quiet early Sundays.
