50 mile 2024 – will be refreshed for 2024 !!!


50 mile course – one feed station – Green signs

Perfect for first-timers, two challenging but achievable climbs with enjoyable descents and plenty of beautiful rolling countryside.

The 50-mile route takes a gentle climb out of Marlow towards Frieth and Fingest which will ease you in gradually. The first climb of the day is Oxford Road. The bottom of this climb is the toughest, once you’ve completed for the first 100 metres you’re past the worst. At the top, you are rewarded with fabulous views of the Hambleden Valley and Turville (filming location for many TV shows including Midsomer Murders, Vicar of Dibley, Lewis, Miss Marple, Jonathan Creek).

Now a steady, gradual climb up to the highest point on the route at Stokenchurch followed by a glorious, fast descent, exhilarating for even the most reluctant of downhillers.

Once you’ve crossed the B4009 continue on the A40, then back on to local roads and a short climb up Clare Hill. Through the picturesque villages of Cuxham, Brightwell Baldwin and on to Ewelme followed by the second major climb of the day Swyncombe Hill which takes you up to Cookley Green.

From Cookley Green the route heads along the B481 towards Park Corner and Nettlebed, then on to Highmoor for a well-earned pitstop and then Rotherfield Peppard, through Sonning Common, Binfield Heath, on to Playhatch and over the river Thames at the stunning Sonning Bridge. You may have to wait at the lights but it’s worth it just to take in the beautiful surroundings. Then Charvil, Twyford and Waltham St Lawrence, White Waltham, and a steady climb up towards the Cookhams followed by a steep descent down Quarry Wood, complete with an alpine style hairpin bend. Now just a short triumphant ride over the iconic Marlow Bridge to the finish at Marlow Sports Club, where family, friends and well-wishers will be waiting to welcome you back.

The route may be changed at short notice due to road works and other unforeseen circumstances therefore to be on the safe side we recommend that you leave it as late as possible before downloading. In any event, we will have plenty of signage and marshals en route.
