The above Resistance Distribution, is based on our estimates of a male podium finisher. We’ve estimated this to be an athlete with an output of 7.7 Watts\/kg. With a total mass of 70kg, averaging 540 Watts. Our predicted time for this rider is 3mins 5 seconds.<\/p>\n\n\n\n

The forces acting against each rider is very individual. By far the greatest force is gravity. It is no suprise that as we increase a rider’s weight, so does the proportion of energy required to move the rider up the hill. However there may be some interesting changes to the distribution of the other resistances.<\/p>\n\n\n\n

How does resistance change for different riders<\/h2>\n\n\n\n

Let’s face it, at 15% average, gravity is a huge part of the battle between Watts and Speed. However, with a few trips up the hill for our myWindsock Virtual Rider, we can see how each rider’s morphology has an individual mix of additional resistances to pay attention to.<\/p>\n\n\n\n

Increase Mass of Rider, bike & equipment<\/h4>\n\n\n\n

Keeping our Watts\/Kg the same, let’s see how three riders of 60Kg, 70Kg and 80Kg compare. Here we see an exchange in distribution between Air resitances and Gravitational resistance. <\/p>\n\n\n\n

Look at how air resistance decreases, whilst gravity increases as a proportion of the rider’s energy consumption. Heavier riders are less affected by changes in the wind. See also, despite the power ratios being the same at 7.7Watts\/Kg, a larger rider actually rides the hill quicker. <\/p>\n\n\n\n

Increase Rider’s Power Output<\/h4>\n\n\n\n

Taking a 75Kg rider we then altered their power from 5Watts\/kg up to 8Watts\/Kg. As the power increases, the proportion of Air Resistance increases the most. <\/p>\n\n\n\n

Here we see a similar exchange between Gravity and Air resistance. It’s interesting to observe that a less powerful rider will be impacted more by their bike and equipment weight. <\/p>\n\n\n\n

Also see that as a rider becomes more powerful, Acceleration increases as a proportion of energy expenditure. This is the energy required to change the rider’s speed. As power increases, rotational weight becomes more important.<\/p>\n\n\n\n

Conclusion<\/h2>\n\n\n\n

You may not be able to change much about your morphology. At 6ft 2inches, I wish it was something I could train around September and October. However understanding your individual fight up the hill may give you some idea as to where to focus for that extra edge.<\/p>\n\n\n\n
