Yesterday a good round of tennis. I won 6-1. Today a 11.6K (according to iPod). First 11.5 went ok from knee’s perspective. Then, just 100 metres to go, I’m running on a slippy trail, home in sight, and my balance slips for a quick second. Result: huge pain in the right knee! Too damn bad. Does this mean another two weeks of less than 50K per week? Today’s run was the longest one since marathon. And I was hoping for running 100-mile weeks already in November…
