There's another school of thought - ends to middle.
The top speed stuff starts at accelerations, 6 sec hills, sleds etc, then moves to 60s, 80s and up to 120s. 3 (or maybe 4) x 120 flat out is a seriously tough session for someone running them fast and can take 3-4 days (or even more) to recover from.
Then the endurance part is long to short.
I like 400 programming to be done this way too.
To the HS coach who only has people for 10 weeks, I am assuming boys and girls - boys in the 10.8-11.5 range (21.8-23) and girls a second slower in the 100.
I would do something like this for the first 4 weeks (and following).
Monday top speed - 60s at submax (though fast) for the first 4 weeks, gradually get faster and work on firm. Week 5 add 80s, week 6 100s, weeks 7-8 120s. For the 400 specialists, add sleds.
Tuesday gym - power- not going to write it out but Olympic lifts, other glute/hammy work like nordics, core etc.
Wed
(a) For the 100-200 runners accelerations -plyos, short (6 second) hills, sleds if you have them., up to 30m sprints (don't get to top speed the day after gym)
(b) for 400 types, you get to do special endurance. No time for a proper base. First 4 weeks do (week 1) 3 x 400 on 12 min recov at about goal 400m time + 4-5 seconds (2) 3 x 350 6 min recovery similar speed or 1 second slower, (3) 2 x 450 15 min recovery similar speed (4) 3 x 300m 12 min recov at goal 400 speed. If you had a 3-month GPP this is where you do 4 x 400, 3 x 500 etc, but no time in a 10-week program. Then you can almost alternate 2-3 x (200+150) with 30 seconds and 15min recovery and the 3 x 300s (probably the classic 400 session) and also 10 x 100m at 95% of max with 5-6 min recov - can be brutal (distance runners might not think som ut try doing them at 10.7 speed x 10.
Thurs - off
Fri speed endurance - all 4 reps with 10 min recovery. week 1 40 sec runs, week 2 30 sec, week 3 20 sec and week 4 150s, getting faster each week. The benefit of running time rather than distance is it's equally difficult for all (male/female). Running 300s is harder the slower you are. The following 4 weeks do same progression but one less, faster with 12 min recovery.
Saturday gym - strength
Sunday -off - so roller, stretch and do some core. The 400 specialists can do some extensive tempo like 200s at 70% o f race pace if they are keen. Alternatively the 400 guys can do their tempo Sat morning and gym Sat evening, then have Sunday off (my preference but not always practical)
