While doing intense cardio (like RPM classes) how high (heart rate) can you go before it becomes too much (too hard for your heart, too catabolic, etc ) ?

is it 80% of your max heart rate ? 90% ? 100%
 
No.

Just hydrate, eat right. The bigger problems are usually your other muscles (legs) needing recovery time.
