Considering only the physics of bicycling, that's true. But I'm thinking of the added strain on his pulmonary system in supplying oxygen and nutrients to all those fat cells. It's not the same as wearing a backpack filled with 50 lbs of rocks. That would be bad enough, but being fat means that his body is expending a lot more energy than mine just keeping those fat cells alive.

I'm not worried about his lungs. His heart though

I am kind of in the same boat. I ride clipless on road, have for years. I never really liked clipless off-road..... About 2 months ago I thought I should give it a try again. Voile! I like it. Maybe it's the new pedals (I am running Time ATAC instead of Shimano 858s), I don't know, I am sold.

I still ride platforms on my DJ........ and trials.

I can't understand how he could ride so fast and have so much endurance, given all that extra weight he's carrying around. Wouldn't that be an enormous liability for a bicycle racer?

Endurance and body fat ratio are not directly proportional. Look at Sumo wrestlers and long distance ocean swimmers....both typically have body's that would look to be fat to most people, but both also have great endurance.

Fat is not really using that much oxygen at all..only enough to exist. Fat is a secondary fuel source for the body. Its the muscles that use the oxygen in doing their job..and obviously carb storages(glycogen in muscles). Fat is also lighter than muscle or bone..so the "extra" weight he is carry is deceiving as far as its actual weight.

Food for thought.

There are two instructors I know who swear by flats, but their ultra-aggressive style of riding doesn't really lend itself to clipless anyway. They do things like dragging a foot while cornering and change foot position a lot when riding, which clipless pedals aren't designed for. I find that I have to concentrate on my pedaling technique a lot more when riding clipless off road, but the 20% power increase is well worth the effort. And of course I no longer have to worry about my feet slipping off the pedals when the bike is bouncing around under me, or when shifting gears aggressively.

Danger. Pain ahead

Against my better judgement, I've tentatively scheduled the Texas Rando Stampede 1200. They run this one every two years and while their site hasn't been updated yet, it'll kick off on 5/1/13.

750 miles, < 90 hours (hopefully), Texas Hill Country....what could possibly go wrong?

Rugby season's started up, and my cycling's had to go straight out the window. No more time for hours on the bike.

Anybody got a good cycling workout that takes about 20 minutes? I might have to buy an indoor trainer.

20 minutes is just warm up to get the legs loose and blood circulating. I'd say at minimum an hour for short intervals if you want a focused cardio workout. 4x10 min aerobic threshold with 5 mins rest (endurance level) between sets. Or the standard 2x20 with 10 minutes rest between sets. 20 minute warm up, 50 minutes workout and 20 minute easy spin = 1.5 hours. That's about as short as I can make a workout and get anything useful out of it.

Looks like I'm buying a trainer & cycling indoors at night, then.

That is what thought as well. Then I read that over 80% of the WC downhill guys use clipless, all of the top 10. I figured if they could do it, so could I....

They did give me the inspiration to try it again though.

Clipless on downhill? That takes some balls.
