Did the Olympic Park run yesterday. The stadium and the other buildings (esp the velodrome) are amazing, although the bulk of the run was on service roads so it felt like running on a nearly-finished building site in the main.
The track in the stadium is HUGE, and the stadium itself is ok from the seats but incredible from the track!
Time was 42:48, which is was reasonably pleased with for 5 miles, given the 1st mile was very congested and took me 9:49.
(bear in mind my fastest 10k to date is 57mins, although that was last October).
Next up, Balfron 10k.
