About the Tour des Trois Vallées

2024 will be the 52nd anniversary of the first “Dieppe Raid” Cycling Weekend which is now known as the Tour des Trois Vallées, the three valleys being those of La Scie, La Varenne, and La Béthune rivers.

The event is a set of cycle routes organised by Cyclo-Club Dieppois  on the roads and lanes of the countryside in and around Dieppe, offering various distances (from 30 to 140 km) to suit both families as well as  keen club cyclists. A walk is generally offered for non-cyclists. With the exception of 2020 and 2021, when the event was unavoidably cancelled due to Covid, the event has been held every year. 


The event was started in 1972 by Neville Chanin, a well-known British cyclist who travelled widely throughout the world by bicycle. It was established in commemoration of the infamous Dieppe Raid of 1942 where our Canadian allies suffered such terrible losses. To learn more about the history of the Tour de Trois Vallées  and Neville Chanin visit our history page.  

It is a great way to introduce less experienced cyclists to cycling in France with its quiet and well-tended roads and gently rolling hillsides along the three river valleys.  At the other end of the spectrum, many keen club cyclists also come back every year The routes may be ridden on any type of cycle (road, mountain, or hybrid) and children are welcome. Each year there is normally at least a few cyclists from Evesham Wheelers, London Clarion Cycle Club, BedWell Wheelers, Sussex Nomads, South West London CTC, and Team BB.  




Dieppe is a beautiful town with its picturesque port, long esplanade, chateau, and an excellent selection of bars and restaurants. It is known throughout France for the quality of its seafood dishes combining fresh fish and shellfish with Normandy cream and butter. It has an excellent swimming complex on the seafront with a 50 m outdoor pool, various indoor pools and a spa. The ferry is less than a mile from the town centre so it’s possible to leave your car at the ferry port in Newhaven and travel by bike on the ferry. If you have panniers then that's great but many of our group travel with a bag on their back for the short distance to the hotels. 




Club des Cyclotouristes Dieppois (CDC)


This club was founded in 1982 by Lucien van den Brook with the aim of promoting more relaxed cyclotourismas opposed to the focus on racing of other local clubs. For many years they have taken part in visits to England for Sunday rides with local clubs in Sussex. They have been organising the Tour des Trois Vallees since their inception and, despite now fewer numbers, they remain active, organising many rides along with“grimpettes” (hill climbs) in and around Dieppe.


First Things


  1. ​Register for your ride and for Sunday dinner (optional)

  2. Book your travel and accommodation. 


The Entry form and details of how to book for the 2024 event will be published soon. There will be four routes:  30 km, 60 km, 100 km and 140 km. We plan to organise an informal dinner this year on Sunday evening (details to be announced shortly). ​​


Travel  and accommodation need to be booked individually by entrants. It is recommended that participants arrive no later than mid-day on the Saturday in order to attend the Welcome and Event Briefing (see below). Most people arrive on the DFDS Newhaven-Dieppe ferry who have given our cycle-only passengers a 20% discount on the fare. However, Eurotunnel is also a popular choice; Calais to Dieppe is a 2-hour drive.


There are a number of hotels in Dieppe itself and Airbnb properties abound. 




Event Schedule


Saturday - Welcome and event briefing (5:00-6:00 p.m.)


This takes place at the Salle Municipale Paul Eluard (5 rue Thiers) [link here to Google Maps?]. Riders sign in and receive a welcome pack containing a route sheet and map. CDC run a cash bar serving drinks.   Following words of welcome by representatives of the town government  the event organisers present how the following day’s events will unfold and answer questions. The session typically lasts about one hour. In the past, tombola tickets have been given out; that’s likely to be the case this year too!



Sunday - Setting off (from Salle Paul Eluard)


Riders set off between 7h and 9h according to the route they have chosen and their abilities.  Cycling out of the town, riders follow the supplied route sheets and maps. In addition, at points where two routes separate and at key junctions CCD will have put markings on the road to indicate the route direction.  Nowadays, many riders follow the route on GPX files which can be downloaded to navigation devices here [GPX Files will be added soon]



Walking routes


There are traditionally two walks organised starting from Salle Paul Eluard at 9 am. The shorter one is around the centre of Dieppe and the other walk takes in the surrounding countryside and is just under 10 miles. The routes and distances of this year’s walks will be published as soon as they have been agreed. 



​Mid-way refreshment stop (St. Aubin-le-Cauf)


A refreshment stop with energy snacks, sandwiches and drinks will be set up along the Avenue Verte (former railway and now a lovely bike path) where it enters the village of St. Aubin-le-Cauf. This is funded by your entry fee. The stop opens at 11h30 and closes at 13h30. 



Awards presentations (Salle Paul Eluard)


Starting around 5:00 p.m.  there is a prize presentation where awards for various categories and exploits are given. In years past this is when the tombola prizes are also given out, so look out for this! This session typically lasts 60-90 minutes.



Dieppe tends to be very quiet on Mondays. There are no events planned. Most participants return home on on the 11h ferry for Newhaven.
