Randonax entries close on Saturday 26th August when all remaining GPX files and rider packs will be emailed to entrants.

We have emailed out the first 150 GPX Files and Routesheets and will send out the late entrants’ ones on 26th August, so if you entered after 17th August you will only get your files around 24 hours before the event. We are not promising entry on the day, if there are any places left then entry on the day will be £15.

We will not be sending any GPX files out between 18th and 26th August nor responding to any emails over that period

We have the Finisher’s Roundels, your free reflective mudguard sticker, the rouesheets and GPX files ready, the Brevet Cards are being allocated and the weather seems to be getting better … fingers crossed!

We have checked the routes and will keep an eye on the local HS2 works, but the info to date suggests that the routes will not need amending. If HS2 overruns we will supply a detour GPX 24 hours before the event, but we do not anticipate this happening.



With so many entries already, we are looking forward to the Bank Holiday Randonax Rides more than ever, and weather forecasts look promising. We are pleased to note that the HS2 works at Harefield should not affect the ride, so are not anticipating any route changes. Venues are confirmed, roundels and stickers are ready and we anticipate sending all entrants their GPX files and route sheets about 10 days before the event. If you enter after 17th August you will only get your GPX files 24 hours before the event.


Just £10 entry, each finisher receives a woven roundel / patch (scroll down for image) and reflective bike frame sticker. Food included at start and finish, and three great routes to choose from at 200km, 100km or 70km.

It all starts from St.Martin’s Church Hall, Eastcote Road, Ruislip, HA4 8DG in West London. Free parking opposite in municipal car park in St.Martin’s Approach

The 200km route, heads out into the Chilterns towards our cafe control at Pitstone before heading back to pass Whipsnade Zoo and take in the iconic Ivinghoe Beacon and another climb before passing the Great Train Robbery Bridge. It then continues westwards to loop Thame and climb back up the Chiltern Ridge en-route back to Ruislip. About 1,900m of climbing in 200km with three significant climbs. The 100km route, shares the 200km route to Pitstone (cafe stop) through the Chilterns but then turns Westwards and loops back through some classic Chiltrern lansdscape climbing to Wendover Woods (the highest point in the Chilterns) and passing the Roald Dahl museum. The 70km route is a classic Chiltern route encompassing Chesham and Hawridge before returning via  Chipperfield, no particularly challenging climbs, but manageable hilly terrain with some nice lanes.

200km starts 8am

100km starts 8.30am

70km starts 9am

ENTRY VIA BRITISH CYCLING £10 (plus £1 fee) or £15 on the day.

A super fun audax style spin featuring a choice of three rides in the glorious Chilterns. Finishers will get one of our sought after patches / roundels as a trophy, all included in the (petite) price. It’s a value for money, not to be missed, gala occasion celebrating West London Cycling’s second birthday; A Bank Holiday Bash brought to you by the same person responsible for the legendary May Day Chiltern Audaxes from Ruislip in years past. Expect the same fun as those, but now a British Cycling event.

This is an Audax style event and isn’t for beginners, no signage nor rescue but who needs those in the era of bike computers and mobile phones? There will be free refreshments at the start and finish with a GPX file to navigate from and a Route Sheet as back up, all for just a £10 entry fee. Bring your own bars/gels etc for the ride, or stop at one of the cafes en-route. Entry may be available at £15 on the day if spaces are still available.

You can ride at any speed you like, but we would expect you to average between, say, 15kph and 33kph depending on your chosen ride / fitness / what you did the night before.

Like an audax, you get your Brevet Card stamped at our cafe stop control, answer a couple of simple questions on the route and write the answers in your Brevet Card (which is also stamped upon completion). At the end you get to keep your Brevet Card and also get cloth patch / roundel to prove you did it and keep as a prestigious souvenir … oh and the mudguard / frame sticker which is relective and enhances your visibility.

We will email you a GPX file of the route during the fortnight leading up to the event, together with a route-sheet for you to print out as back up. You will need a bike computer (eg Garmin or Wahoo) to load the GPX file in to. This is easily done by synching a Wahoo with Strava or Ride With GPS etc (free online) or using Garmin Connect if you are a Garmin user.

It’s fun, fun, fun with 70km, 100km or 200km options.
