The equation for total aerodynamic drag force on a bicycle is well-understood and, you're right, air density has a role in it: the higher the density, the greater the drag. As you guessed, density decreases with increasing temperature so warm air is less dense than cold air. It's also probably no surprise that density decreases with pressure. However, ...


If you have a power meter than download something like Golden Cheetah to analyse the data. Otherwise, if you are just using Strava's predictive data - I wouldn't bother as it won't be accurate enough for detailed analysis.


You could try looking at your ride through Veloviewer which offer a lot of very nice ways to dig into your data.


(too big for a comment)...not a real answer, just a partial: From UCI part 3: 3.2.039 The rider on the inside of the track, unless overtaken, shall lead at least at walking pace and make no manoeuvre to force his opponent through until reaching the pursuit line on the opposite side of the track. A maximum of two standstills shall be permitted for each ...


Air density alone has a fairly substantial impact on speed, if all else is equal (and if my calculations are correct!) Based on the equation and from this page on cycling aerodynamics, and the air-density values from Wolfram Alpha, I came up with: At 300 watts, at 0*C, will travel at 39.34 km/h At 300 watts, at 10*C, will travel at 40.06 km/h At 300 ...
