Rowing Machine 30:00  7.51 km (4:00 / km)
2nd time on the erg this year, and I'd say better.
Splits were solid at 1:59-2:01 throughout - certainly not hot, but there was no dropoff at all. Muscle tone is good for the erg, but I've done no back exercises - that's one deficiency. Anyway, ergs don't float and they don't orienteer, so I guess I'm doing OK.
