Measuring recovery

Nothing much planned for Easter Monday so decided to do a gentle recovery run with Rob and Jack Finch. Also took the opportunity to mark out some measured runs for future rep session. The recovery run was about 5 miles in total - slow jog.
First measurement (using the trusty Garmin) from the letter box on Halterworth lane, down through Tadburn meadows to the climbing wall is 600m
Next one, 800m from the entrance to Tadburn meadow (by the wall again) running on the flat all the way along the stream until the end of the fence (on the path up to Hestia close).

We then jogged over to Fishlake meadows to the start of Robert Whitwoth drive. Its about 2 miles from the clubhouse, so not too far for a warm up.
I've been looking for a flat, well lit, safe area do do reps during the winter and this looks to fit the bill nicely.
If you start at the entrance to RWD and run along Fishlake meadow road its a 300m straight run on a wide flat, well surfaced path. Perfect for high tempo running. Then take a left in RWD and follow it round until you hit the mini roundabout. That's exactly 800m. This is then a short walk back to the start.
This area would be perfect for multiple 800m reps (6x800m with 1 min recovery, running at 5K pace for instance). You could also do a speed session with 300 fast, 200 slow, 300 fast, 1 min recovery (repeat about 5 times) or 10x400m with 1 min recovery.
