The Deeside Night Cup race in Glen Tanar on Wed night set competitors some tough technical and physical challenges, with nobody able to claim a clean run at the end of the night. Despite that, Jake’s sub-60’ performance on the long course was impressive. Pete Lawrence took the honours on the short course.

8 runners on the long course used Loggator tracking units during the event. You can review and compare their routes by going to https://www.loggator.com/events/UoEK7ssWNg02bbF9

Note that in this instance the “mass start” option is not functional as the runners were not pre-allocated start times. If you select all of the athletes and do a “replay” you will see where they ran and who was with whom at different stages out in the forest.

To interpret the routes and analyse performances in more detail the Loggator traces can also be imported into 2DReRun and 7 of the traces from Glen Tanar (there appears to be an internal error in Alistair’s trace) are now listed from:

In this piece of software a replay of the runners can be followed using a “mass start” and different routes can be compared for different legs of the race.

Leg 4-5 on the long course proved decisive for many on the night. The important thing here was to ensure you chose a line that passed some distinct features, such as the flat area below the large crag, just south of the straight line, in order to get a good attack point into the control. Runners that went above this crag found themselves coming off the hillside with little to navigate by, and subsequently lost a vast amount of time on the hillslope.

Leg 5-6 was also tricky, with the potential for significant time-loss looking for a single crag on a big steep hillside. Most runners avoided major mistakes here, but the fastest time was achieved by staying low along the hillside, going quite close to the track, before climbing into the control.

On the night the route choice leg from 7-8 was removed as the burn was still too high to cross and runners were asked to punch an additional control at the bridge on the north most track.
