Okay, so maybe whacking my knee on a big rock was less than ideal - and I won't pretend it didn't hurt. But my whole body (aside from from my knee) feels amazingly loose, relaxed, soft and balanced after a challenging 5km run along a fairly technical trail tonight. A bloody, scraped knee seems a small price to pay to feel this good.
To be clear, I am completely. Totally. Absolutely. Smitten with trail running. Everyone should try it. Seriously.
