When I followed a 5k race plan I had a really wonderful session that was 4x800m fast with 2 minute rests. For a speed session I loved it.
And so to the new version of this on my HM plan... 12x800m fast with 30 second breaks... OMFG that hurt. The running was fine in the second half of each session, but those breaks were so short that all they seem to have achieved is breaking my rhythm!
Garmin heart rate zones:
Zone 1: 2%
Zone 2: 3%
Zone 3: 6%
Zone 4: 46%
Zone 5: 42%
Which doesn’t add up to 100% so maybe I spent a little while in cardiac arrest 🤣
So, it was the rests that nearly broke me today... straight run next time out on Monday!
