Master's runner needs 0.5 seconds in the 200m in two weeks

negative split the race, obviously.

also, when you do your lean at the finish do a really strong toe-off like a jump to get an extra .5 seconds. if it's properly timed, you'll do well. although you've probably heard this but first 30-50m is short strides increasing your speed, then carry out your first 100m in around 14.5 and last 100m in 14 or faster.

You said you ran 29.08 recently. Wouldn't that be the record? Or was it not a sanctioned meet? Anyway, I would just do that again.

Practice your weaknesses. In your two weeks to prepare, practice your starts and then top speed with some flying 30s and 40s. Other than that make sure you are well rested for the meet.

The FAT 29.08 was at an all comers meet. I have to run it at the Senior Olympics State Finals to count.

first off, if your start is poor, either use Moye blocks or no blocks at all. Second, plyometrics and 40 meter sprints would be the only thing that could teach you to activate more muscle groups in 2 weeks.

Standing long jumps into a sand pit (or on grass)

Frog jumps

High skipping

Bounding (long skipping, going for distance each stride)

And with the 40 meter sprints, focus on keeping your upper body and torso still while pumping your arms and driving your knees.
