The defaults for this calculator predict 22.77 mph at sea level: http://austinimage.com/bp/velocity/velocity.html Raise the elevation to 7,350 feet and the speed prediction rises to 25.19 mph, about 10% faster. Someone who pedals daily around the Arkansas River at about 4,900 feet enjoys a predicted 24.36 mph and a 1.6 mph advantage. Of course, thinner air might reduce the rider's aerobic function and power. Cheers, Carl Fogel |

Carl, not to leave the topic but where is the Arkansas at 4,900' ? Decimal Degrees? During you cyber travels, have you stumbled over a comprehensive American rivers map or program? g. daniels |

During your cyber travels, have you stumbled over a comprehensive American rivers map or program? g. daniels Dear Gene, The Arkansas River is at 4,900 about half-way down the face of the dam at the Pueblo Reservoir: http://www.crh.noaa.gov/ahps2/river....i ver+Page%21 My daily ride goes west up the river to the dam, up to the top of the south side of the dam, about 200 feet more up the ridge west of town, and then back down along the south river bank again and up onto the bluffs: http://i19.tinypic.com/4kynamo.jpg I'm sitting at the 4750 foot contour line on top of the south bluffs here, where the line goes rightward into the gray residential zone: http://terraserver.microsoft.com/ima...28&Y=10589&W=3 My daily ride drops about 50 feet down to the river, shown as 4697 at the upper left, then climbs to about 5100 feet, so 4900 is about average. Water flow and reservoir height readings may matter more in arid south-east Colorado than in Florida: http://i4.tinypic.com/7yrl0fa.jpg The daily report this morning shows the Pueblo Reservoir at 4858.10 feet, John Martin Reservoir downstream at 3805.13. The precision seems absurd until you realize how much water a hundredth of an inch rise means to dry-land farmers from here to the Mississipi when the reservoirs cover dozens of square miles. Colorado and Kansas lawyers spend their lives squabbling over water rights. As for detailed elevations of rivers, I don't know of any specific maps, but the high-resolution topo contour lines on the maps at http://terraserver.microsoft.com will get you reasonably good information. Cheers, Carl Fogel |

Interesting riding.
Can you recommend all star downhills? for total ambience not sheer drop or max speed. I down l;oa76=((EXded google ert yesterday so river tracking was easier than Gmaps. the river track seems easy: algorithm wall depth wall, label with name( muddy, white green, kikapoo, brule, elk fox...), project. I don't know about cross section for altitude/drop: wether that's derived or developed. Next week. water here is the big deal. Tho sand perks, the lay is flat so once fallen water doesn't run it just sits there. That's what all the ditching was about. Collier, remember? Advertising: faster lower longer wider no cypress trees, no Everglades, no Florida Bay. My pet NOAA dam is the one a Sidney Lanier. I guess I'll drive thru and ask about the green crick |

I love Merckx because he did it without all the aero stuff. Also enjoyed Indurain breaking the hour record in 1994 with one of the poorest form I've ever seen. Just to think, if only he had great form. It's sort of have been a tradition for the winner of the Tour de France to consider the "Hour Record". Waiting for your man; "TT/Climber Specialist" Lance to do it. -tom |
