My wife and I car share, so it was either my bike or my legs to get to work some days! I like to balance the two with a few car days of my own. I also set myself a goal to complete a HM.
Mistake? Starting my run too quickly!
What I know now? someone I can't,recall got it spot on when they said: it doesn't get any easier, just faster! Also, that races bring out the best in my running! Oh and plasters on nipples for long runs are essential!
