Cycling 46:00  17.0 km (2:42 / km)
Plan A was to get out early in the morning before going out to check matters sprint-related. Plan A was a fairly immediate failure, plan B (try again in the afternoon) was a bit closer to success but still not quite there, so plan C was to get on the bike instead, for the Yarra Boulevard session. Didn't feel crash-hot early on the bike either (quad was uncomfortable on the climbs), but was going at a reasonable pace (by my standards) and improved as it went on. Reasonably hot (low 30s) which is a bit easier to handle on a bike than running, too.
The sprint has the perennial headache of construction sites which may or may not stay stable, but is otherwise looking good. Paid close attention to the minimum size of mapped features, something which has not been the subject of any controversy at any event in which I've been involved in the recent past.
