All I know about wind (and the @$%*#@! wind we have here in MN seemingly all the time):
- It's a workout going into it.
- It's a blast with it at your back.
As long as a burn my calories for the ride (my primary goal) I don't care which....although the speed with a good 25mph constant MN tailwind is really a blast. Nothing like matching that fast wind at 20+ mph and barely hearing any wind rush as you pedal, looking down and seeing 25 mph on the speedo. Greatest feeling in the world....for this amateur noob anyway.
When I get the itch to race I'll probably care more.
