Treating "competitive cyclists" as this single unified group (with three subgrouping) belies some prejudices. Like all walks of life there are a diversity of people, all with different motivations, morals and life experiences. As such there is no single correct answer your various questions. For example: are people in pelotons generally friendly, ...

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, ...

Replace "cycling" in this question with any competitive sport. How should we know if it's right for you? How should we know what the community of cyclists near you is like, or whether or not you'll get along with them? Enter a race. Did you have fun? Enter another one. Or don't. Your call.

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.

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 watts,...

(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 race....

BMX bikes are all very similar. Short, stout frames, tall handlebars, 20" wheels (and maybe the occasional 24" for a very tall BMX rider), and wide tires. The difference between Supercross and Freestyle BMX bikes is in the gearing. Supercross bikes will have a higher gear ratio for getting up to speed in races, while Freestyle bikes usually have a lower gear ...

Take the plunge and try it! Either you'll find that you don't enjoy it or you'll have discovered a wonderful new aspect to cycling. Regardless, you're only out a race fee. Community The cycling community is just like that of any other sport. You have some people who are pros, those who were, some who wish they were, some who think they are and some who don'...
