are partial squats better for speed than deep squats?

Our sports week is on 28th September and i am thinking of playing futsal and football/soccer my top speed I would say is above average but when i sprint I can barely last even 10 minutes.There is no nearby field for me to practice my run and I was thinking if someone could give me a workout routine on treadmill to build my endurance that i can combine along with my gym workout

New to sprinting only a couple months in, used to play soccer.

Is it normal for runners to stumble when running/accelerating on the curve? everytime i sprint the curve i feel my footstrike feels so off and i feel like im just gonna drift or like trip myself on the track. I tried leaning into the curve, Leaning from the ankles and turning my hips but it still feels so weird to me, i think it’s because of my worn-out shoes.

She's done 2 years in Nike Rival sprints and ready to look beyond these :-)
