The weather forecast was spot on, 95% chance of rain and it was. Anyway I was out of the house so committed to my usual 13km cruise to Oxstones. When I first bought the Garmin HRM-Tri I was interested in the R/L contact balance especially as I was always lop-sided. Then I forgot about it and noted that I was drifting closer to 50:50. Today's run is interesting in that I averaged 50:50 but started off to one side and moved across to the other.
