Running

Split the race into km chunks. Assuming you've got a time target in mind, this breaks it down nicely for doing the maths, and I find it less mentally challenging than counting down each and every lap. If you get the intensity just right, seeing 7 laps still to go can feel quite tough. And as ever, don't go off too quick. It's amazing how the first lap of a track race can feel really easy, but keep an eye on your 200m split and rein it in if necessary.
