HM @24 80% HRR

Had a thought last night to do a HM this morning - so as I actually managed to get up on time I got into work with enough time to get it done - initially I thought about a 1:54 pace - then 1:50 - started and hit 1:48 so stuck with that but as the wheels started to wobble I steadied it by turning it into a 9-% HRR row and ploughed it out.
