did sprints last week on wednesday too. think it was around 50 meters. ran it 5 times and that was pretty good. did it after basketball and a few jumps. one day i wanna just show up to a track and do a full sprinting session though, but not sure how i'd do it. i think a good way to do it is to start from shortest distance to longest. maybe 100m 5 times, then 400m thrice, then time myself for a mile run? does that seem like too much or too little?
well for the mile, you'll probably be pretty toast after 5x100 & 3x400.
I personally like separating those into separate sessions.. in your case for example, that'd be a day of 100's, another day of 400's, and another day for a mile (or more).. but that's if you were adapted to sprinting/running.
so in the beginning i think the most important thing is just keeping the volume low and not going 100%... ie, you can run 5 x 100m but, just go ~70-85% or so.. it's still fast but not maximal enough to really wreck you (hamstrings for example).. I'd say a good month of just incorporating some speed/distance sessions but keeping it light/relaxed would be good before you consider intensifying things.
so for now, just split up your ~100-400m sessions and >= mile sessions .. so that you aren't running a mile or more after fatiguing yourself from 100-400m submax sprints.
initially i'd stick to <= 200m for sprints though .. 400m's can be pretty brutal in your legs/lower legs etc.
Anyway, if you keep it submax, the actual protocol isn't as important right now.. if you want to just go out and run 10 x 100m's submax, you do it.. and if you feel wrecked by #7, you can end that session. Same goes for 200's etc. As for mile runs, your body/brain will pretty much prevent you from overdoing it.. you'll probably run one mile and then end it lmao.
