Power in Watts<\/h2>\n\n\n\n
This is the power you expect to average in each scenario of your route, uphill, flat, downhill. Uphills and downhills are triggered at greater than +2% and less than -2% gradient.<\/p>\n\n\n\n
The average male rider will expect to average 100-150 watts on a moderately paced ride of 2-3 hours. Average female riders will ride at 80-125 watts on a moderately paced ride of the same time.<\/p>\n\n\n\n
If you know neither your CdA nor your power use the Suggest Power Settings<\/a> button.<\/p>\n\n\n\n Drag in CdA is the aerodynamic performance of the rider. An average rider on a road bike hoods will be between 0.32-0.38. A time trialist can be as low as 0.17. Premium<\/a> members, enter the CdA Estimation from past rides here.<\/p>\n\n\n\n The following are ways to estimate your CdA to enter into your forecasts.<\/p>\n\n\n\n Enter the weight of you and any other equipment. A good ballpark figure for cycling is your weight plus 10kg to get you close. If you are using the Premium CdA estimator<\/a> it is best to weigh yourself holding bike for the most accurate estimate.<\/p>\n\n\n\n This is the efficiency of your tyres on the road. Most road bike tyres are around 0.005. Light weight time trial tyres are close to 0.004. For a good guide on rolling resistance for various tyres check out http:\/\/www.bicyclerollingresistance.com\/<\/a><\/p>\n\n\n\n Please keep in mind that the tyre is only one part of the rolling resistance equation. Road surface is highly variable. Think how difficult it is to ride on a field compared to a road. For average roads it is sensible to have a number of between 0.004 – 0.005 as your rolling resistance coefficient. Very rough roads can be as high as 0.008!<\/p>\n\n\n\n A percentage of the Watts that are lost in the drivetrain. If you have measured your watts using a hub based power meter this will be 0%. Most drivetrains will result in a loss of around 3% of your power.<\/p>\n","protected":false},"excerpt":{"rendered":" Your Virtual Athlete simulates your activity for you.

Methods for estimating your CdA:<\/h3>\n\n\n\n
Time Trial Position: 0.17 – 0.25
Road bike (race): 0.24-0.3
Road bike (summer): 0.27-0.32
Road bike (winter): 0.3-0.36<\/li>
<\/strong>Premium members can enter the estimated CdA from previous rides. To get the best estimate check out the advice here<\/a>. Find out more about Premium features<\/a>.<\/li>
<\/strong>If you have a power meter choose a route and course you have completed in the past. This should be a relatively flat route and the start and finish should be roughly the same point. Ideally loops or out and back courses. Now enter the average power and your weight from a previous effort. Adjust the CdA until the Ground Speed is roughly what you would expect for your ride.<\/li><\/ol>\n\n\n\nWeight<\/h2>\n\n\n\n
