Same O loop twice, both rounds as hard as possible. Aim was finding out how much time is lost/used for orienteering - second time you know the course and controls pretty well. There was no control flags and it made first round more difficult.
I recorded both rounds with GPS (Forerunner 205).
Map , routes, dot race
1st round: 22:33 Boomed finish.
2nd round: 21:57 I tried to improve my route choices, but only one of them was faster. I lost the path to #1
Both rounds: asthma trouble - speed wasn't good so there was plenty of time to read map. It made difficult to run an faster even if I knew well where I was going.
