My weekly trip to the track fell through due to other commitments so my new training window was 8:30pm. It was raining and there was a bit of wind about, plus I was going to have to try and run some intervals under street lights. Any sane person would have pulled the pin.
During a 2.2km warm-up, I decided to run some 400's. As part of the warm-up I marked out a section of the N17 that looked to be about 400m (with lampposts as my start and end point). After a few strides it was time to get this over with.
The first effort was a feeler (running towards the city into a wind). The time was 84 seconds so clearly it was more than 400m. At least that is what I was telling myself. I continued on changing direction after each effort with the luxury of one minute walk/slow shuffle recovery. Coming back I was 81 seconds (wind on the back). That pattern continued throughout the set of 16 with me running the return leg slightly quicker. The wind picked up a little throughout which made the outward section tougher. Looking at the times I averaged 82 seconds and the effort level felt like I was running at 3 minute km pace so I guess the actual distance to be closer to 450m. So clearly I have no idea how to mark out a 400m distance.
I finished up with a 5km warm-down. All up 14.4km for the session and lots of strange looks from other users of the footpath...
Matt, just as well your runnin ability is better than your couses measurin ability! Good luck next weekend
