I finally managed to post a time for Nick Spår.
42:30 according to Strava. I could take a lot of time off that with a little more knowledge of the course and a little more effort. Most of the technical sections are now OK; my main failing was in measuring my effort. I could have easily done another lap directly after I finished.
The unfortunate reality however is shown below:
The track is now very, very wet and unlikely to dry out until next year.
MTB season is over.
Time to swim, Row, Run and hit the trainer.
