If you only want to ride long travel bikes. If you only shuttle or ride park. If you smoke like a chimney. If pedaling uphill and hike-a-bike do not do it for you. Then do not even bother reading the rest.
But if you’re a fan of trails with views. That a ride with at least 80% of singletracks is what you are looking for. If you dig technical descents. If you secretly dreaming of having Graves calves. If your motto is no pain, no gain. Then XMB is for you.

I discovered this new style of racing last fall. I had just moved to Sospel, in southern France, and didn’t know anybody to go ride with. So I bought a local map and began to explore the local trail network. I must admit that coming from the U.S., I’m addicted to Strava. Not only for the pseudo competition but mostly to discover new trails and I use it as a training tool. After uploading a few rides I did in Breil -sur- Roya, in the next valley over. I saw that three of my favorite descents were segments with the name ” XMB – descent”. A quick Google search and I found the XMB challenge website. From February to May, there are 4 events in the Alpes- Maritimes.
To sum it up quickly, each race has at least 1400m of ascent, almost all on singletracks for 35/40km. As Enduro season does not start until the end of April, it seemed like a good plan to get in shape.

The first round took place this weekend in Aspremont, a few kilometers inland from Nice. The day before the race, I suddenly wonder what I got myself into! I was sick all week and go race XC was perhaps not the best idea. In addition, while preparing my racing bag, I find myself packing my XC kit. Something I have a hard time admitting owning and even more wearing in public. And then, I realize there is 1400m of ascent in 29km, it’s going to hurt! So I decided to use my XC/trail bike: a Blur TrC (120mm rear travel) with a Revelation adjustable from 120mm to 150mm and a lockout system. And I also added a pair of shorts to cover my chamy.
On race day, I found out I wasn’t the only undecided one as to what to wear and what equipment to use. You could see everything from semi-rigid to 150mm and even a few freeride bikes. There was XC riders, all club-clad, with matching kits and a bunch of Enduro racers such as Yoann Barelli, Thomas Lapeyrie and Aurélien Giordanengo coming to test their winter training.



The atmosphere was friendly and we all met in the center of the village for the liaison to the start. Just 3km on the road plus a bit of hike-a-bike, not a bad warm up before the race.
The race is pretty brutal and if you go for GC, it is better to have trained all winter and have an XC background. Time is made on the climbs and not descents, even though the latter are awesome in this race format.
It was an interesting experience, although Enduro is definitely more my thing, as I do not have to worry about my time on the climbs. But once I get in better shape to race XC, I will give it a go. And above, just go ride it again as the trails were beautiful.
