How to run it
Run 20 km at long run pace, a touch slower than you might like. Start slower still for the first few kilometres. Carry water, or plan a loop past it, if you'll be out for more than an hour.
What it's for
The long run builds endurance: more capillaries, more fuel stored in your muscles, and legs and mind used to being out for a long time. It is the backbone of every race plan past 5K.
