Plausibility of a sub 50 400m by 18 years?

aight first you need to acquire a pair of spikes.

What does your training look like right now?

Well I normally try to get in 3-5 miles every morning before school.

Apart from that-

Mondays- tempo run

Tuesdays 4 200m repeats w 20 second breaks- thought this would increase muscle endurance. Do this maybe 2-3 times

Wednesday- 5 100m sprints 3 200m sprints and one 400m Sprint

Saturdays- interval training between my 400m pace, all out Sprint pace and jogging pace

Sundays and Thursdays I often go for football coaching, with Friday being my day to catch up on school work. In retrospect this schedule does seem kind of dumb, thoughts?

how much of puberty have you gone through yet

are you fully developed physically or do you still look like a middle schooler

Haha about 180cm, people say I look seventeen, minimal body hair tho

swap monday and tuesday, stop running so much in the morning (unless you want to become a 400/800 runner) and get in weightlifting sessions instead. explosive stuff that helps improve your running economy.

If you want to follow a professional plan, Clyde Hart was former WR holder Michael Johnson's coach. Here's a link (obviously adjust the paces to your goals):

Good luck!
