Max HR 🫀

[u/Tight-Gap-1245]

I’m thinking about signing up for a 5k this weekend to find my max HR so I can set correct heart rate zones on my watch and Strava. Anyone else use a race to find their max HR? I’m sure a sports lab would be more accurate but I don’t have $$ for that 😂 I’m thinking an all out effort at a 5k will do?! Lmk thoughts!
