4by1k r24

Decided to do the 4by1k r24 today (scheduled for weekend) as its a short session and easier to fit in at lunch

HR monitors (both Suunto and Garmin) playing up and pissing me off - nearly binned session cos of that - but due to the fact I'm calorie counting that would mean no dinner - sod that

1:34.9 (set of with target of 1:36.8 in head - I was faster)
1:34.8 - had to go faster than first
1:34.5 - thought I'd done 1:34.6 in the second one lol)
1:32.7 - decided to thump it

all bang on 24 strokes per minute ;o)
