A Strava Tour of Flanders sportive preview - 6 key climbs you need to know about

Riding the Tour of Flanders sportive? Here’s a guide to six key climbs on the route

The Tour of Flanders (Ronde Van Vlaanderen) really needs no introduction. It's one of the most iconic races on the cycling calendar, made famous by its short cobbled hills - hellingen in Dutch - and is one of the biggest sporting events in Belgium. While the professionals race the full 259km from Antwerp to Oudenaarde, amateurs can tackle a choice of distances in the sportive that runs this Saturday, the day before the pro race. 


It's a perfect cycling weekend and is massively popular, with cyclists from all over the world taking part, and in excess of 16,000 cyclists crammed onto the narrow roads of the route. More and more British cyclists have been making the short trip in recent years.

You can choose from four distances to choose from in the sportive, the longest is 237km so it doesn't quite replicate the full pro race. There's also a 200km, a 141km that is very popular as it does most of the key climbs, and the shortest option is 74km.

If you’re riding it for the first time, you might be wondering what to expect? The Ronde is famous for its short and sharp cobbled hills, the likes of the Paterberg and Oude-Kwaremont made famous by battles between the top classics specialists over the years. The number of climbs and cobbled sections has changed over the years: there are 18 climbs in the full 2017 pro race route, with a number of changes. The Molenberg, Valkenberg, and Kaperij have gone and in their place is the Tenbosse, Pottelberg and the iconic Muur. You can view the full list of climbs and their location on the full race route below.

Strava is a very useful tool for previewing routes and climbs. We’ve used it to pick out some of the main climbs so if you're doing it for the first time, you can have some idea of what to expect, from the distance and gradient. Even if you've ridden it before, the segments give you an idea of what a quick time is. You can also filter the data for each segment, and view it be people you follow, age groups or even weight, to get a better indication of what a good goal time could be. 

We've picked out seven key climbs to preview using 3D renders from the excellent Veloviewer website.

David worked on the tech team from 2012-2020. Previously he was editor of and before that staff writer at RCUK. He's a seasoned cyclist of all disciplines, from road to mountain biking, touring to cyclo-cross, he only wishes he had time to ride them all. He's mildly competitive, though he'll never admit it, and is a frequent road racer but is too lazy to do really well. He currently resides in the Cotswolds, and you can now find him over on his own YouTube channel David Arthur - Just Ride Bikes
