Sprints day today on what felt like the hottest, muggiest day of the year!! Went to Alexandra Rec Ground across the road from where i live. Nice and convenient and the oval circuit is dead on 600m, plus, as a bonus it keeps me away from the heavy traffic and in a lovely park. I managed a WU of 2.4ks, then 7 laps at approx. 3:50k/h pace then a 1200m WD. That was enough for me at this stage. Legs were definitely feeling heavy and fatigued by the end of it and i was ready to stop.
