Cycling day trip from St-Malo to Rennes

Route: St-Malo to Rennes

Get ready for a scenic adventure across Brittany, starting from the historic walled city of St-Malo and finishing in vibrant Rennes, the region’s capital. The ride covers just over 92 km and takes you through peaceful countryside, following mostly quiet roads (around 64%) and some scenic cycleways.

You’ll leave the salty breeze of St-Malo behind—don’t miss a walk on the ramparts before you set off—and pedal inland, rolling through charming villages and green landscapes. The route is a gentle roller, with a total ascent a bit over 500 meters, never getting too steep (the highest point is only around 105 meters).

Expect a good mix of surfaces: over half is smooth asphalt, with a few stretches of gravel and unpaved paths—nothing too wild, but a gravel-ready bike will be more comfy than skinny tires. After a good few hours spinning through Brittany’s heartland, you’ll arrive in Rennes—a lively city with a great café scene and plenty of Breton culture to celebrate your ride.

Perfect for a day of adventure, a taste of history, and some well-earned galettes at the finish!
