Racing with Sore Quads

1) don’t do this again

2)stretch and roll out a lot, but don’t over do it to the point you’ll pull a muscle. stretching will only do so much

3) take some advil or something 2 ish hours before your race if it’s still bugging you

4) don’t psyche yourself out. if you think you are gonna do poorly, you will do poorly. odds are once you get warmed up and get some adrenaline pumping, you will be good and forget about it. just stay composed and run your normal race strategy.

You are young, and you will repair quickly. By tomorrow, you won't feel nearly as sore. Get a really good night of sleep! But, just so you can lose sleep worrying: The soreness is from microtrauma, and it takes a full 7 days to repair. Racing 'hard' before day 5 is a good way to disrupt the repair process, and instead of new muscle growth, you end up with new connective tissue tangle growth, "scarring"...at a 'micro level'. Do that a lot, and you'll hamper your performance later in life.

Dry cupping and professional message might help.

Talk to your coach. Tell them just what you did here, went hard on Thurs. and are still sore. There’s no magic, you’ll recover as fast as your body can (adequate calories & sleeping are the biggest here).
Askthem if you should do anything differently in the race.

Not sure what you consider a big meet. Unless the team needs you to score in order to move on to the post-season, probably not that big a meet.

Better to have sore quads then to have quad sores. You don't want monkey pox.
