My achilles tendon had not been happy on Monday and Tuesday morning. Quite why I ended up doing quite a large double program on Tuesday, I don’t really know. Stubbornness, I suppose.
At lunch, I did a 10km loop around the Petrusse and Alzette valleys near work. I tried to stay on forest trails as much as possible, which means running on a softer more uneven surface almost 50% of the time. I went quite slow (6:44 min/km), although it still felt like I put in quite some effort. The 240m of elevation change didn’t help, probably.
This was also my first outing with my new Garmin 910XT GPS watch and cadence monitor. It was interesting to finally see detailed statistics about how many steps I take while running. Turns out that my cadence on this run at least was quite a bit lower than the 90 to 100 steps per minute that a lot of people seem to recommend. Now sure how my average cadence of 80 fits in with that, or if I’m still in the “reasonable” range because I’m taller than your typical lightweight distance runner.
In the evening, I did a lone sprint training (the others were doing starts, which I can’t do yet): 8x300m with short breaks was the plan. I ended up doing only 5x300m, which is when my running form went to hell. My left achilles tendon was probably really happy about that too, although during the runs it didn’t feel too bad. I wasn’t very fast, just cruising along at a speed I thought I could maintain without too much pain in the hip or achilles tendon: 53″9, 53″5, 52″0, 54″3, 51″6.
The left achilles tendon (or rather, the insertion near the heel) was not happy at all once I had cooled down at home.
