Phew, it's really tough for me
1st two rounds: constant speed to get ready for sprinting 4
rounds
3rd to 6th round: sprint as much as possible
7th to 9th round: constant speed to get ready for
sprinting 3 rounds
10th to 12th round: sprint as much as possible
on the last 100m, i will spread my arms wide like the girl in
the show Titanic---I'm flying
