Breaking the Law of Averages, Part 3: Let it ride or let ‘er rip?
When riding your bike, your finish time will improve if you push harder into the wind and relax when you go with it. The trick is knowing just how much harder you can push and how much to relax…
Breaking the Law of Averages, Part 2: Wherever the wind may blow, you probably lose
We all like to think that we can buy gear or come up with a strategy to “cheat the wind.” But the math shows that you cannot make up time lost riding into the wind by riding faster with the wind at your back. See why.
