After the upcoming rest day on Monday, the Tour de France really gets exciting. If exciting means cruel, gruelling and painful to watch. Yes, that’s right, Le Tour is off to the mountains.
The race takes a jaunt through the Alps, with respite for the climbers on the Individual Time Trial on Thursday, before an uphill finish on the Giant of Provence, Mont Ventoux the day before Paris.
You may have noticed I’ve been referring to climbs by a category number, and I’m sure, if you’re like my Mum, you’ll be wondering what these category numbers mean..
The categories are divided up into Category 4 (being the ‘easiest’), 3, 2, 1, and HC (Hors Categories, or ‘Outside Category’ - being the ‘hardest’).
The category of a climb is established by a committee but ultimately decided by the race director - currently Jean-Francois Pescheux - after taking into account several factors. These include:
- What is the altitude of the climb? (How high is the mountain above sea level?)
- How high is the peak’s elevation? (How high is the peak of the mountain in comparison to the surrounding terrain - how much does it tower above?)
- How long is the climb? (What is the distance of the road the riders’ travel?)
- What is the highest, and what is the average gradient? (How steep is steepest section of road, and how steep is the road on average?)
- Where does the climb feature in the stage? (Is it early on, when legs are fresh, or later on when riders are tired?)
- What is the condition of the road? (Is it dusty, gravelly, likely to get slippy if it rains?)
Be aware that as the Tour is the Mac-Daddy of races, so a climb that is seen as a Category 2 might be a Category 1 in any other race. With this in mind, a general overview of category climbs would present the following:
Category 4 - A hill. On a slow stage, any rider worth his salt would make it over still breathing through his nose. Obviously I mean any Tour de France rider. I would’ve gotten off and pushed by now.
Category 3 - Usually around a 5km climb, at a 5% average gradient. Like the kind of local climbs you would find in the UK or USA. Or avoid, if you’re anything like me.
Category 2 - A tricky one to define - harder than a Category 3, but not to the white knuckle extent of a Category 1, like Stage 15’s Cold des Mosses which is 1445m high, with a gradient of 5.5% over 19km.
Category 1 - Usually a much longer climb, but still at a relatively low gradient of around 5%, like Stage 16’s Col do Petit Saint Bernard which is a 27km ride over a gradient of 4.6%.
Hors Category (Outside Category) - A climb that doesn’t fit into the previous categories, often very long and quite steep like Stage 20’s Mont Ventoux, which is over 1900m high, and reaches gradients of up to 11% over a 23km route.
