Glen to Glen Half

A quiet loop of the national park before the field joins the marathon route. Flat, cool, and usually still under mist at that hour.

Onto the Military Road and up towards Glenmacnass. This is the whole of your climbing, in one honest stretch.

Turn at the waterfall and run back down the valley to Laragh. Fast if your legs allow it — and a lot of runners find their first sub-two-hour hill half here.
