Paterberg

Length: 400m
Gradient: 12 per cent (avg) 20 per cent (max)
KOM: Eli Iserbyt 53sec

Riders ascend the Paterberg twice on the 260.8km route: once with 51km to go and again as the last climb of the day, 13km before the finish.

With 11 climbs already in the legs when the riders first go up it the 20 per cent gradient is tough, but in the heat of the final kilometres it becomes even harder.

Taaienberg

Length: 800m
Gradient: Seven per cent (avg), 18 per cent
KOM: Daniel Oss 1-12

The Taaienberg is by no means the longest climb on the route, but with a gradient of 18 per cent in places and coming 36km from the finish it’s a prime place to make an attack.

Kruisberg

Length: 1,825m
Gradient: Five per cent (avg), nine per cent (max)
KOM: Daniel Lloyd 4-03

What the Kruisberg lacks in steepness it makes up for in length. At over 1,800m long the climb takes over four minutes at a crucial point in the race. With 26km to go to the finish the action has more than heated up by that point.

Koppenberg

Length: 600m
Gradient: 13 per cent (avg), 22 per cent (max)
KOM: Cameron Bayly 1-39

When it comes to cobbled climbs, few can compare to the Koppenberg for difficulty. Again, it’s not massively long, but with gradients of up to 22 per cent it’s an incredibly challenging climb, even for the professionals.

There’s only one ascent of the Koppenberg in the Tour of Flanders, but it comes with 44km to go, so no-one can afford to take it easy.

Oude Kwaremont

Length: 2,500m
Gradient: Four per cent (avg), 12 per cent (max)
KOM: Niki Terpstra 4-55

The Oude Kwaremont may be incredibly long, but thankfully it’s not hugely steep. When you’ve climbed it three times, though, you may be glad to see the back of it.

Sitting at 2,500m long, it is the second and also the penultimate climb in the race, with riders also taking it in at the 54km to go mark for good measure.

Kanarieberg

Length: 1,000m
Gradient: Eight per cent (avg), 14 per cent (max)
KOM: ‘Strava athlete’ 2-24

Unlike the other climbs on this list, the Kanarieberg is slightly kinder to the riders in the fact that it’s not cobbled. With the standard of Belgian asphalt, though, that might not make that much difference, but it’s slightly less bone jarring.

At 1,000m long, the climb is the final climb before the brutal final section. It comes with 70km to go, but all the hills after it are pretty unappealing and are all cobbled.
