Chain Slips out when I try to go really fast

Title says it all. I ride on a slightly taller bike so when the chain came out I panicked (totally forgot I can slow down the bike with the front wheel) and put my toe to the ground and now my shoe has a nub haha. This has only happened once because I never pushed my bike to that limit again but of course I am looking to fix it.

Any suggestions?

Please clarify.

Fixed wheel, coaster brake, or what?
Slips out how? do you mean it falls Off?

If is is falls off, a photo of the bike, specifically the area from crank to rear wheel would help. That along with the specifics regarding the age and condition of drive train components.

If by "slips out" you mean you threw the chain off the rear cog then I'm guessing your chain was too loose to begin with. Make sure your chain has proper tension by moving it further back in the track ends. 1/2" of play up and down in the chain should be fine

Make sure your chainline isn't borked.

Whats type of chain you are using? single or multi-speed chain? and chainset?

Multi-speed type chain by itself, its not problem for single speed uses if you set chain tension correctly.

Whilst single speed chain type tend to be more forgiving if you set it to be more slack and it won't fall off easily 'unless' you hit a deep pothole and your whole bike up-down like crazy, chance the chain will pop.

Also chainset, must be sure you uses the one designed for single because its safer for many reason.

Sounds like you need some brakes until the rest of your rig is squared away. Check to see if your chain, cog, and chainring are too worn. Make sure you’re putting enough torque into those nuts, too.

Chainring might be off-center/out of round too. That can make it more susceptible to getting thrown at higher speeds.
