another new low - 60r20 HRR 70%

So woken at 5:00 by the baby so once I settled her I checked the HR again - 33 this time - another drop - keep this up it will be 0 in May - oh wait?

So this morning plenty of time and got 60r20 in pre work - HRR 70% on the new limit of 143 - all well apart from a blip near the start - putting that down to the strap needing a new battery maybe - in fact - can you replace the batteries in the Garmin or do I need a new one?
