Well that settles it - 17km slow and steady safely banked this morning with barely a skerrick of complaint from the knees. In fact if I wasn't already well over my allocated mileage for the week I would have kicked on for the half mara distance, but as it was I packed it in after two hours feeling frustrated that I couldn't allow myself to go further. But that is, after all, a bloody good sign.
So the problem with the knees clearly has a lot more to do with speed than distance, i.e. I can cover the longer distances with little problem if I take it slowly enough, but race pace or tempo runs causes some grief. Guess I'll just have to sneak up on the harder speed work very carefully indeed.
Anyway, I'm delighted to have knocked off more than 40km this week... a good week's running by my standards.
And as I'm writing this, our Brighton marathon champions should be fast asleep getting nice and rested for their race in the morning. Best of luck everyone - I hope to get there myself one day. Time will tell.
So tomorrow's another week and another mixed schedule of short, easy, tempo, hill climb and long slow runs. Can't wait!
