Road bike (Tandem) 1:11:22 21.71 km (18.3 kph) +261m
ahr:121 max:148
Tandem ride with Dawn from Whitchurch to Cowbridge
I decided to try the Ultegra LHS Stages Powermeter on the Tandem front (mine) XT crankset. First problem is that the Ultegra stages LHS crank is 172.5mm and the XT crank is 175mm. I decided to ignore this.
I've always known that powermeter readings are higher on the road than on the turbo so the time recorded in each of the zones below (from TrainerRoad) are likely to be inflated.
Also worth noting that I generally use the PowerTap for turbo sessions which will have different power to a Stages because it is in the rear hub. This is due to power losses in the drivetrain from crank>chain>rear hub.

It was our first tandem ride since April 2018 (Dawn told me) when we rode with Haydn and Jan.
Dawn was nervous with plenty of calls to slow down! [She told me to write that she did well.]

Tandem ride from Cowbridge to Whitchurch (after an hour with Pam)

Discovered that I will need spacers on the crank spindle in future as it was moving back and for. The Ultegra LHS Stages crank seems to use 2-3mm less of the spindle length than the XT crank.
The return leg felt easier; probably due to not having to cycle into a headwind!
