I think that 25 minutes measurement must have been for the upper portion of Ventoux. The complete climb from Bedoin is reportedly 5251 ft., and Armstrong did it on 2002 in 58 minutes. That's a climb rate of 90.5 ft/min. According to Chris Carmichael, Lance averaged 4 beats below his lactate threshold on the climb, so he could have gone faster. Hey, I can do 90 ft/minute. For about a minute. -- terry morse Palo Alto, CA http://www.terrymorse.com/bike/ |

Indeed, a world class sprinter (runner, I mean) can keep pace with the peloton on the flat for a short burst. What the Tour's running spectators really show, I think, is that there is some point at which a hill becomes so steep that you can run up it faster than you can ride. Cyclo-cross competitors tend to run up steep sections that are still technically rideable. They do so not because they couldn't ride up if they chose to, but because it's faster to carry your bike and run. -- Dave... |

How is this relevant? Now you're comparing aerobic efforts of a fresh club cyclist who can sustain maybe 250 - 300 watts to a pro who can maintain about 400, even on a mid-tour climb. Let the club cyclist sprint uphill for maybe 10 or 15 seconds, and he'll be faster than the pro's average climb speed. The fat guy in the devil costume is running in only very short bursts. The pro cyclists aren't going to do a mid-climb sprint to drop him. > >>Likewise, almost anybody could outrun the best marathon runners, when the marathoner is >>maintaining his pace and the other guy is sprinting some short distance. > > > Sprint at sub 5 minute mile pace?

The running spectators don't show this, though, since they are running for a few seconds, not for hours. These same spectators would not be passing the bikes if doing the whole climbs, even the steepest ones on the grand tours. Dave Lehnen |

From rec.sport.unicycling 10/5/03: "Wow, what a great day. It was a textbook example of PERFECT weather for the 22nd Mt Diablo Challenge this morning. 'The Mt Diablo Challenge' (http://www.mtdiablochallenge.com/) is a nearly 100% uphill road race, about 11 miles, about 3300' (1000m) of climbing. No cars and GREAT views. 7 unicyclists and at least 700 bicyclists showed up this year." "The (unofficial) results for the unicyclists: 1) Glenn Drummond - new world record, approx 1:13. He was delayed at least 30 seconds in a crash near the start too. Glenn was riding a carbon fiber 36" unicycle he made with 165mm cranks and shaved down Crupi pedals. He has drilled 2000 holes in the Airfoil rim AND gone tubeless. His seat and Reeder-style handle are a single piece of carbon fiber. He runs 14ga spokes meaning that there is only one item from Coker on his cycle - the tire. All this attention to weight results in a complete cycle at 13.5 pounds! I think he could lose a couple more ounces by shaving the tire too. It's not just the ultra-light unicycle - his incredible fitness is what allowed him to break the record by approx 4 minutes. WOW! Just call him Mr Anaerobic. Also he's over 40, so old guys CAN crank."

A road with less wind and > > a more consistent grade should produce an even higher climb rate. > > isn't this a HS physics problem? watts is watts. Dear B.C., Watts is watts, but like many real-world questions, this one has all sorts of odd possible complications. Imagine the same 170-pound person doing both the riding and the running. On a 17-pound bike, he'll have to raise an extra 10% in terms of weight. There's also a small wind drag increase from the bicycle. It's very little at such low speeds, but the drag from even a feather-light inflated balloon model of a bicycle would slow a runner down a bit. (Stop me before I propose timing my brother-in-law the marathon runner, with and without a pair of water-wings.) Then there's the big question of what happens when steepness increases past the normal grade for a bicycle. Runners and walkers can go up grades that may well not be possible to pedal. I gather that the bicycle stair-climbers are hopping and balancing, not grinding. Throwing yourself and a bike into the air repeatedly (and coming down) means actually lifting the weight far more than just walking steadily uphill. Jump up, lose height, come down, fight for balance--I get tired just thinking about it. In any case, it's hard to find a nice set of figures showing increasingly steep hills and times for either the same person (imperfect because the same person rarely does as well both running and walking) or for the best in the world at each sport (still imperfect because the best riders in the world often do climbs, but the best runners usually concentrate on marathons, not on what they would consider weird climbs). With a shallow enough climb, the bicycle seems to win (though we bicyclists boggle at considering Mt. Washington or Mt. Ventoux shallow). With a set of stairs up a building, the runner seems to win. (The Empire State Building's stairs are steeper than Mt. Ventoux's bicycle route.) Most of the thread is wondering at what point things shift and why. Naturally, we're much more polite than Mr. Flannery and Mr. Morehouse: http://www.gutenberg.net/etext99/pgpgs10.txt "Pigs Is Pigs!" Carl Fogel |

I mean, a unicycle should weigh HALF of a bicycle, right? One of my bicycles weighs under 20 pounds (or did when I bought it, anyway), and people with more money to spend (and lighter loads on their bikes) have bicycles weighing 16 pounds or less. In fact, the m2racer company has a racing bike that they claim weighs under 10 pounds...they should be able to create an 8 pound unicycle for him. http://www.m2racer.com/info.php I wonder how light that bike would sans derailers/shifters/etc, as a single speed. In fact, go fixed, and remove brakes; instant 5 pound track bike, eh? >I think he could lose a couple more ounces by shaving the tire too. That sounds like a good way to get up a mountain. Shave body, wear less clothes, urinate before riding, eat less the day before...you can really get rid of some grams! -- Rick Onanian |

Dear Terry, Well, in baseball pitching, yes, we mere mortals can aspire to a 60 ft/s, which is about 41 mph. Sixty feet per minute is undoubtedly what you meant, about one foot climbed per second. Only someone who makes as many innocent typos as I do should point this out. I use this page to check whenever I'm not calculating in the familiar furlongs per fortnight: http://members.aol.com/javawizard/numbers.html It instantly converts whatever you type to dozens of other measurements to about ten places. Now I'm guaranteed that someone will read my idle chatter in hopes of catching me out. Cheers, Carl Fogel |

I think Jonathan Vaughters may still hold the record for a Ventoux ascent, at 56:50. He did it during the TT for the 1999 Dauphine, from Bedoin (roughly, 1600m elevation gain in a tad more than 21 km). |
