Notes
Well, again, it depends if you regard fartlek as a high-intensity continuous session which fluctuates remorselessly around your lactate threshold until you are at last left crumpled with exhaustion ...
... or if it means seven Sixth Formers (depleted numbers this time) jogging around Wandlebury with a couple of not-far-from-tempo loops of the ring ditch thrown in. 3:25 per loop = 6 min miling (0.57mile loop).
