<p>My friend and I did a local club race sunday, most of the fireworks were on the early climbs so we were able to compare our files after.  Atthe top of the climb that produced most of these numbers, he and another rider were maybe 75m ahead of me.  He weighs about 140 and has a 14 lbs bike, I am 178 and have a 23 lbs bike.  It's an interesting illustration for the effect of mass when climbing a hill:</p>

<p>the faster lighter guy</p>
<pre>
10 second - 601
<span class="moz-txt-citetags">> </span>20 - 505
<span class="moz-txt-citetags">> </span>1 min - 475
<span class="moz-txt-citetags">> </span>2 min - 462
<span class="moz-txt-citetags">> </span>5 min - 351

<p>me, the slower heavier guy</p>
<pre>
10s-745

<p>Damn near linear at 10s but less so over time</p>
<p> </p>
<p>124%</p>
<p>117%</p>
<p>112%</p>
<p>106%</p>
<p>109%</p>
<p> </p>
<p>for a 25% weight gain</p>
<p> </p>
<p>Someone more mathy than me might be able to predict what my 240lbs of me + bike might need, but I'd guess (based on same linear extrapolation and I'm another 25% more weight) something like</p>
<p>923w</p>
<p>693w</p>
<p>593w</p>
<p>518w</p>
<p>417w</p>
<p> </p>
<p>Which means I better swim a hell of a lot faster than you guys to get some time on the boards <img alt="" src="http://files.kickrunners.com/smilies/dontknow.gif" style="width:37px;height:15px;" title=""></p>

<p>Good thinking Ron.  My ability to make power seemed to trail off after about 3 mins and I was able to catch a draft on another rider to close back to  the leaders before that rider blew.  Since the climb was only 3 minutes in length, I guess there was never a block of 5 minutes steady where we did much work.  By the time we hit the long climb there were just 4 of us left and the skinny guy got a flat, so we just kind of rode along.  </p>

<p>Interesting to compare the numbers, my friend is able to climb much better.  Much, much better in fact, i can do OK sprinting and cyclocrossing.</p>
