It was too beautiful a day to resist. Breathless, slightly chilly, but glorious spring sunshine; perfect running weather. And I had to go into town anyway, so I slipped quietly out of work and tried a cautious mile down to the bike shop. And I didn't collapse in agony on the side of the road. My knee held up pretty well, perhaps feeling very slightly sore in the last 100m or so. And I didn't seem to have forgotten running form, and with lots of things to think about it may even have improved. Fast into the knee drive... and then let the ground come to you - be patient. I was worried this would slow that hard won high cadence, but no, spot on 180bpm, straight out of the box. Running (even!) taller, straighter - could I feel those fitball lunges coming into play? No idea of pace, no idea of HR, but it felt effortless. I could imagine running 50 miles with that kind of efficiency. And, oh, the feeling of sun and wind on face and skin.
There's lots still to do, particularly on getting this knee strong. It's not just building up the non-existent quads - it's getting them to fire appropriately - they have an annoying habit of sagging on the slant board, even with my knee locked out - I have to watch them in the mirror and consciously tense them up again. But it's getting there. I can even do pistol squats, provided I've got support on either side so that the knee doesn't take all my weight on the way down. Cheating? Probably, but it feels like work and the right muscles are getting tired.
Blah blah blah.
