Good to see other post on here, like it, at it again this week no change in weight,wind speed was 14kph,distance came out as 10.03km,time 65:03 HR average 130, not any real change from last week then.Did a test run for my max HR because it is almost a year since my last one and it is a bit lower so from now on will go for an average of 128 +- 2 bpm
