Hills are the bane and the salvation of the road cyclist. They’re hard, sometimes agonizingly hard, and yet without them road cycling would be unbearably boring. I’ve had the good fortune to have ridden some of the great Tour de France climbs in the French Alps like l’Alpe d’Huez and the Col du Galibier. I’ve also ridden 30 miles of prairie road that was dead flat and straight as an arrow. If given the choice, I’d ride the climbs every time. Climbs are the yardsticks by which experienced cyclists measure themselves while new riders often look on them with fear and loathing.
This is one of a pair of posts designed to help new riders climb. I’ll look at some riding techniques in Hill Climbing 102. In this post I’ll examine pedaling and shifting. There are many different approaches to climbing and riders at different stages of development will tackle a climb differently. A new rider who is desperate to survive to the crest will climb very differently from an experienced racer trying to drop the competition on the steepest part of the climb. Hill Climbing 101 and 102 are written for the relatively inexperienced cyclist who might benefit from some information about basic climbing techniques.
Cadence. Cadence refers to how fast your feet go around on the pedals and it lies at the heart of cycling whether on hills or flats. Most cycling computers measure cadence in revolutions per minute (rpm) although cyclists will often speak of cadences of 90 or 100 and leave out the “rpm”. There are two basic approaches to cadence: Spinning and mashing. Spinning means pedaling in a small (easy) gear at a high cadence while mashing is pedaling in a big (hard) gear at lower cadence. In very rough terms, spinning will generally build cardiovascular fitness and endurance while mashing will build strength and bulk. Mashing is also more likely to produce muscle and joint (especially knee) injuries. As a very general strategy, spinning is usually better than mashing although there are so many different kinds of riders and different kinds of road conditions that there will be many exceptions to this general rule. The typical recommendation is to spin at cadences of 85 to 105. This may be a difficult cadence for new riders to maintain but it is good to practice until you can comfortably ride in this range. When climbing, it is best to spin at a high cadence in a small gear. Many times you may find yourself climbing in your smallest gear so you can’t shift into an easier gear and spin at a higher cadence. However, as your fitness improves or the gradient of the hill lessens you can begin to ride in bigger gears. When this happens, work on achieving a higher cadence on the climbs before you work on climbing in a bigger gear.
Maintaining a steady effort. If there were one bit of advice that I would hold out as the holy grail of long-distance riding technique, this is it. The idea is to put forth the same amount of effort consistently throughout the ride. One way to do this is to maintain a steady cadence. You adjust for changes in gradient, road conditions, wind, fatigue, etcetera by changing gears and keeping your legs going around at the same rate. This means that going downhill you gear up into bigger gears and accelerate; going uphill you gear down into smaller gears and decelerate. Many riders try to maintain a constant speed rather than a constant effort going uphill. They tend to exhaust themselves on the steeper parts of the hill and then lose momentum on the flatter parts of the hill. On many hills the gradient will become a bit less steep for the last section before the crest. The rider who is focused on speed will ramp down their effort as the climb becomes less difficult. When they back off the effort they often back off too far, lose momentum, slow down and find it difficult to switch from slowing down to speeding up while they’re still climbing. The rider who is focused on maintaining a constant effort will kick into a higher gear when the gradient eases up and fly over the crest.
Pedaling in a circle. Once when riding in the Washington DC AidsRide (340 miles in 4 days to raise money to help those suffering from HIV/AIDS) I was riding alongside some inexperienced riders giving them help and encouragement as they climbed a long hill and I suggested they pedal in circle. As he struggled to keep going, one of riders looked at me like I’d lost my mind and said “Isn’t that what we’re doing?” Surprisingly, the answer was “no”; his feet were going around in a circle but like most inexperienced cyclists he wasn’t applying force to the pedals all the way around the circle. As much as you can, try and exert force all the way around the pedaling arc, not just on the downward push. Push down, pull back at the bottom, lift up and pull through at the top. This is not as easy as it sounds and it is a skill that takes a long time to master. However, climbing is difficult enough without trying to do it with only part of your available muscle power. You’ve got a whole leg and 360 degrees of arc to move it through. Use the whole thing. Pedaling in a circle is impossible if your feet are not connected to the pedals. It’s much harder to do with basket-style toe clips because when you pull back at the bottom of the pedal stroke, you pull your foot off the pedal. You really need clipless pedals to take full advantage of pedaling in a circle.
Gear shifting. This is perhaps the most difficult hill-climbing skill to develop. When there is load on the chain, such as when you’re climbing a hill, downshifting to an easier gear puts more strain on the chain and the shifting mechanism than shifting up to a harder gear. You’ll often need to downshift to an easier gear during a climb but if you don’t do it soon enough, there may be so much stress on the chain that you can’t make the shift and then you’re stopped dead in a gear that’s too big to get up the hill. On the other hand, if you downshift too soon, you lose your momentum which can turn an easy climb into a hard one in the blink of an eye. You can feel this happen if you downshift to an easier gear and suddenly your feet are spinning on the pedals and meeting very little resistance. It’s all about timing. The trick is to relax your pedal stroke for a brief instant and shift into the easier gear a split second before you have to so that you can put forth the same effort throughout the climb. The only way to get good at this is to practice. There’s nothing like a perfect climb where each shift comes smoothly at precisely the right moment and you feel like you’ve just flown over the hill as if it wasn’t there.
Climbing is hard but learning to climb is worth it. During the AidsRide I rode up and down that hill I mentioned earlier several times helping riders make it to the top. The hill was the longest on the entire 340 mile ride and many of the new riders had been dreading it since the ride began. I began riding with one woman at the bottom of the climb who was very much overweight and out of shape. Like maybe 100 lbs overweight. In addition, she was riding a hybid rather than a road bike which was making the climb a good deal more difficult for her. About a quarter of the way up, she knew she wasn’t going to make it. I talked to her about the hill climbing techniques discussed here and in Hill Climbing 102 and encouraged her to keep going. Another 10 feet, just make it another 10 feet. She was in agony. Just 10 more feet. The hill had such a fearsome reputation that a good number of people had stopped to stand along the road and cheer the riders on as they struggled up the climb. Someone had parked a van with a sound system in the back near the top of the hill and Gloria Gaynor’s disco anthem “I Will Survive” was booming out. We’re halfway up and the woman was going so slowly that I don’t know how she remained upright on the bike; I had to keep looping around in small circles next to her in order to move fast enough not to lose my balance. She knew she wasn’t going to make it but she refused to give up until she absolutely couldn’t give it one more pedal stroke. Just 10 more feet. Tears of pain and effort were streaming down her face. About 30 feet from the top of the hill amidst the music and the cheers of the onlookers she realized she was going to make it, that she was going to succeed at something that just moments before she believed was impossible. The look that came over her face at that instant was so beautiful and so pure that it made every moment I had suffered building the climbing strength that allowed me to ride with her that day worth it. It was the kind of thing you never forget. Hills will do that for you.
