My dad made a bet with me, and he said if I broke 19 mins in the 5k, I can pick out what car I get to choose, and choose our family vacation next summer. also $500.! So I need some advice. Some info bout me 135 lbs, 5”9, most mileage I hit -40, 5k p.r 20:02, 5k ran yesterday at a meet - 20:17, I usually get tired quickly at the end, and my arms swing across my chest , and I usually get sore throats too. I’m a 16 year old male . My freshman p.r was 24:00 for 5k, sophomore year - was 20:02 , and so far my junior year for my first race was 20:17. I really want to break 19 and I will put in the work for it.
