In short: Great marshalls, 3 laps a bit dull. In full: Great marshalls in horrid conditions. It was a good moderately hard 20 miler, and thus good training. The first lap was quite scenic, but the two shorter ones were a bit of a drag at the end. That may have been influeneced by the horrendous weather during the final lap. Found the traffic to be very considerate of the runners forced out of the curb by the deep puddles that formed in the downpour. I knew where I was going, but was very surprised to see no signage directing people into the university for parking, especially relevant given the congestion caused from the event at the Showground. Also nothing at the finish line except water.
