Physiological rationale for lower cadences while climbing
Would anyone care to explain the physiological rationale for using lower cadences when climbing? Naively, it would seem that if a rider is optimally efficient at cadences around 90 RPM on the flats, this would be the optimal cadence when climbing. In fact, I find that I feel better continuing to pedal at higher cadences when on a climb.
I strongly suspect that these higher cadences feel more efficient to me because I've never trained to use lower cadence (so I continue to reinforce this preference each time that I ride). So, please explain the benefit of lower cadences while climbing; if I understand a rational justification I may be able to embrace lower cadences and become a better climber.
Best,
Dave

Hi David,
Higher cadences are better for climbing so long as the rider has the skill and coordination to do them. Many riders don't have those, so they climb better at lower cadences. Skill and coordination for higher-power spinning require focused practice, which it sounds like you have done.
The exception to the rule that higher cadence is better is of course climbs so steep that you won't have the gears to climb them at higher cadences with sustainable power. If any races you'll enter have hills like that, lower gears are a potential solution, but on hills too steep to spin in gears that it makes sense to have on your bike given all the events you'll do, you'll have to reduce cadence. Train lower cadence if you'll have to race lower cadence. It will never be as efficient as higher cadence in terms of fatigue generated per distance traveled at a given power, but training will at least decrease the rate of fatigue when you are forced to lower cadence.
Knee discomfort in cold
As I’ve gotten older, my knees sometimes ache or I feel a slight twinge in them during the winter when I am outside here in New Hampshire. Once I’ve been on the bike for a bit and warmed up, I don’t feel any discomfort or aches in my knees, nor do I feel anything post ride, it’s just before when I am walking around outside in the cold.
I’m wondering if an embrocation like Mad Alchemy applied to my knees would warm them up prior to a ride and be beneficial. Some general info for you that you might need to know – both bikes have been fit by the same person/ shop, no aches/ pains any other time of year and I’ve never done any serious/ lasting damage to my knees. I run 3x week on a treadmill for 30 minutes and I do specific leg weight training 3 times a week, but do not do leg extensions because I know they can adversely affect the knees.

Hi Chris,
Embrocations that increase the circulation of blood near the skin do nothing to replace a warm up for muscle function, but they could help with warming up the knees in the sense of getting you past your early-ride aches. Riding for a few minutes on a trainer or stretching before riding might also do the same. I'd suggest experimenting with each of those possibilities, and also being sure to keep your knees very warm and protected from wind when riding on cold days.
Finding that ideal weight
Hello,
I'm a relative newcomer to cycling, 6 months ago I bought myself a road bike with the aim of getting back into shape. I have no lofty aims of winning competitions, I'm just looking to not embarass myself complete when i take on a couple of 10 mile trials and a 100 miles sportif in April. I've always kept myself fairly fit through football but I've been pretty bad with my food in past, hence when i started cycling again seriously I was 93kg. I've now got myself down to 83kg and I feel stronger and now follow a much heathier diet. I was wondering what your view of my ideal weight should be? I'm 6ft and I'm 27 years old.
Any advice would be greatly appreciated,
Thanks,
Ian

Hi Ian,
You haven't said if your 10-mile trials with be hilly or flat. If they are flat and you are not concerned about finishing time for the sportifs, then your weight doesn't matter too much. Being lighter lets you go faster and dissipate heat more effectively, but if your goals don't involve winning, those are just comfort issues. If you want to ride up hill faster, being lighter helps to a point. For what it's worth, at your height, the vast majority of successful pro road racers are between 150 and 170 pounds (68-77 kg).
At the high end you find the sprinters and time trialists. At the low end the climbers. Below the low end, you give up power even for climbing. Above the high end you can lose weight without giving up TT or road sprint ability. My suggestion would be to keep riding, improve your diet and let your weight go where it goes. You will certainly be lighter and leaner than you are now, but I would not recommend a particular weight unless you are thinking of competing more seriously.
Redlining while climbing
I'm a 48 year old on again off again roadie who moved to Colorado from Florida this past July. I jumped in with a group riding east out of Denver doing about 45 miles to try and get back in shape. I can hang on the flats and little rollers but always get dropped on one particular climb.
I monitor my heart rate and find that when the hammers down I'm in the 160-168 bpm range, but when we hit the climb that I always get dropped on I'm usually at 186-188 before the top. My legs turn to ballpark franks and I've got to back it down to below 150 beats per minute to recover. Any advice to help keep me from redlining it would be appreciated.
Thanks,
Bob

Hi Bob,
You've been in Colorado long enough to have adjusted to the altitude so you're getting dropped on that hill because you are not in good enough shape one way or another to hang. You are simply going "as hard as you can" for right now, so we need to see what you can do to make more power or improve your power-to-weight ratio.
If you can trade pulls on the flats but you get dropped on the hills, I'd be suspicious that you need to lose some weight. If you'll tell me your height and weight, I can make a clearer judgement on that. (Or figure it out yourself: The vast majority of successful racers fall in a narrow band of weights, roughly 10 pounds either side of a line. If you are 5'10", the average pro your height is 150 lbs. If you weigh that much or less, you can potentially climb, if you have the aerobic power. If you weight more than that, long climbs are going to be your competitive downfall. Super-fit riders riding in lower categories might get away with 5-10 extra pounds. For every inch you are taller or shorter than 5'10", add or subtract 5 pounds.) If the guys you ride with are fit, you need to follow these rules to keep up with them.)
If you can sit in on the flats but not trade pulls, then you are lacking in aerobic power and need to develop that before you hope to climb with the big boys. That means several months of aerobic training, lots of long rides but not too much intensity.
As to advice to keep you from red-lining - That's easy: don't go so hard up the big hill. If you are blowing and then crawling over the top, you might even finish the climb quicker by not trying to stay with the group once they start going hard.
