During last Thursday’s run, I started to experience mild pain on the top of my inside joint of my left knee about four miles into the run. It got progressively more painful, but I was still able to finish the run without much problem. I was limping a bit the rest of the day and the following day, but by Sunday, the pain was totally gone. So I decided to do my Sunday long run and about one mile into the run, the mild pain started again and got progressively worse, but I was still able to finish the 14 mile run. If I was smart, I would have stopped and headed back home when the pain started. For the rest of the day yesterday and into today, the pain has me limping a bit again, although it seems to be subsiding as the day goes on.
I’m not 100% certain, but the best I can tell, I may have a mild sprain to my Medial Collateral Ligament (MCL). I don’t think it is serious because with a couple days rest, I don’t even feel it. I think all I need to do is rest it. Fortunately, I’m still early into my training cycle for the AFC Half Marathon, so I’ve decided to take a full week off from running and substitute my runs with sessions on the bike trainer. I did a moderately intense session on the bike trainer this morning for an hour and didn’t feel any pain, so riding the bike shouldn’t get in the way of my recovery.
This is the first time I’ve experienced this injury and I’m not sure how it happened. Injuries are frustrating, but are a fact of life as a runner. I thought this may be an injury I could run through, but I’d be asking for bigger trouble if I continue to do so. But I think this will only be a minor setback and may actually do me well to get another week’s rest having only run a marathon two weeks ago.
