Time Estimates
France’s Brittany region isn’t known for epic bike climbs, but it is a cycling-obsessed corner of the world with popular véloroutes and greenways featuring rolling hills and shorter climbs. Mûr-de-Bretagne is arguably the most famous climb in all of Brittany, and is a favorite of race spectators due to its steeper 1.1km lower portion which is arrow-straight, making for great viewing.
This climb was added to Zwift’s Climb Portal to be featured in July 2025 at the same time as the pro men would be racing it in stage 7 of Le Tour. As in recent tour appearances (2018 and 2021), riders raced up the Mûr-de-Bretagne twice in 2025 during the finishing circuit of the stage, with the second ascent being the end of the race.
Here’s the matching IRL Strava segment:
I can’t believe they’ve added this short climb which is 5 minutes from my home! One of this year’s Tour de France stages will arrive at the top.
This climb definitely is also in Australia. According to Strava anyway.
Yeah, I just did the “Old Willunga Hill” portal climb and got PRs on both this climb and the one I actually did.
Yeah, it’s because the two climbs follow essentially the same route out of the portal, both being almost straight lines for the the length of the Mur, so Strava matches on both when it scans for segments.
I do have a picture of both segments overlaid on each other but the forum won’t allow me to post that unfortunately.
