*** ‘Sprint’ the last minute; this will only make a few seconds difference. No I mean faster than last time! And those seconds do count. Try and sprint with 2 minutes to go and when you feel your legs going just hold off (slow down very slightly) for 5-10 seconds and then sprint again all the way to the finish.
All the suggestions are starred:
*** 3 stars. IMHO it will work
** 2 stars. It might work
* 1 star. Can’t hurt
X 1 cross. It CAN hurt if done wrong.
