The other day we went for our regular Tuesday night ride. We are down to about 18 miles or so now becuase it's getting dark.
So I started using my MTB for more of a workout. It really is harder to ride 20+ mph with a MtB.
Anyhow, on the last ride, I feel behind with another rider and work really hard to catch up. (We were going over 24 MPH for a few miles) Next day there is a dull ache/pain in my chest.
Does anyone know what this is? Could I have damaged my heart or something? Or is it more of a chest cavity problem (Like I over extended myself or something)
BTW I'm 34 and decent physical condition with no known diseases.
I do no know what my heart rate was during this intense exercise but I work working harder than I ever have done in the past.
