Remember, if you are riding at 25 mph into a 0 wind you effectively have a 25 mph wind in your face. That is not that strong. If you rode into a 25 mph wind I think the average guy would have a hard time going 2 mph for more than a mile, maybe a lot less. Try going 5 mph into that 25 mph wind. That is equivalent to riding 30 mph.
Get prepared for the onslaught, my friend. No one questions posters' claims of wind speed and comes away unscathed.
But regarding your equivalence of 5 mph into a 25 mph headwind with going 30 mph with no headwind, it really doesn't work that way. See for yourself on
www.bikecalculator.com In the drops 10 mph into a 25 mph headwind takes about 220 watts. 35 mph with no headwind takes a whopping 770 watts. Or at least so says the calculator.
