Can you race in your first meet (100/200) having not run at 100% in practice any time before hand, ie: no 100% speed work (flat out sprints) in the relevant past? If you’ve done very little speed work what’s a few sessions that could be useful to prepare for the first meet?
If you haven’t gone max up to now, I wouldn’t start right before your first meet. See how it goes (but be careful and relaxed!). you may do ok in the first meet but feel the effort and go a bit slower in the next one if it’s close. You need to think about how many races you’ll have before deciding just how much max work you can handle. If you have a series of meets close together, they will prob have to be all of your max speed til you get into the next SPP after indoors.
