40r18 re-calibrated HRR 70% - 2by 1min 1r

40r18 HRR 70% - new HR limit of 143 means I need to re-calibrate a little - still came in at 1:50.1 so will hopefully knock that under 1:50 soon enough - also dropped the two 1 minutes in at the end - really just let myself concentrate on technique at the end of the second one - target was 1:28.0 - came in at 1:27.4 r34 and 1:26.9 r35 - quite enjoyed that
