O Sprint race 16:58  * 3.1 km (5:28 / km) ahr:172 max:186 spiked:17/19c rhr:48 slept:7.0 weight:29.9kg (injured)
Started gently. Didn't want to push the calf. I was expecting it to stop me after about 2km like last week. Didn't push too hard as a result. Easy nav flowed nicely. Happily the calf held out. Hopefully can now up the running again.
