Training objective: 3-4 hours of very easy cycling with the heart rate between 120-130 bpm's and the cadence at 70-85 rpm's. Nice ride, but a wonky heart rate monitor. I noticed the beats were at ~140 after our little coffee stop at Arensrus (lekker by the way). I tried slowing the pace down, but it just wouldn't drop. Soon I was going ~12 km/hr on the flat road. What the heck? After a while I rubbed my hand along the band to see if it was a contact issue - and voila! it dropped down to ~106 bpm's. Might be time for a new band (I see this one has a few cracks in it) and/or a new battery.... Lots of great advice from 36One veteran Bles de Wet which will come in handy. Another ride like this tomorrow, then rest on Monday.
