Same day of the week, same time of day, same route and same interval workout i.e. 1k warm-up run, 0.5k recovery, 1k sprint, 0.5k recovery, cool-down interval of 90 second jogging/60 second walking until I decide to stop.
Things I did differently were - long-sleeved top instead of T-shirt (cool wind and 7 degrees), incorporated a few short sprints into my warm-up, started the sprint from a slow jog instead of a standing start, continued the cool-down to reach a total distance of 5k.
Well this was a bit of a weird one today. π€ͺ The sprint was really tough going and it felt slow. My respiration rate was through the roof, but my heart rate was on average 10 bpm less that last week and the whole workout was 90% in Zone 2/3 compared to last week which was 34% in Zones 4 and 5.
A perfect demonstration of what is meant by perceived effort.
According to Mr Garmin, my time for the 1k sprint was 5.50. After synching, Strava says 5.49 but lets stick with Garmin for consistency. This beats last weeks time of 6:21 by a respectable margin π
According to Strava, I also got PRs for 400m, 1/2mile and mile and my third fastest 5k time, despite walking probably approaching 1.5k out of the 5.
How did that just happen? π€·ββοΈ
