Field Surveying (City of London Map) 1:55:00 [1] 16.0 km (7:11 / km)
On bike, visiting most of the streets on the new COL map, finding errors.
Cycle Commuting (In to Work) 27:30 [2] 8.2 km (3:21 / km)
Very hot (>25*C) as travelling in at the hottest part of the day (~1700.) Slowed down a lot at the canal, partly because it was very busy but also because it was so hot.
