Hi, I'm another high heart rate here 215 is the highest I have seen in a controled situation, but I normally back off at about 214 so there is a chance I have a 220 as well. Anyway don't listen to all the people who say bad stuff about a high max, the key becomes can you use that higher heart rate to its full potenial? I have many rides under my belt that are zone 4/5 so it is not a problem to be that high, especailly if you have a high threshold which is almost zone 5 as well. You should find with training it is harder to get those heart rates as you have to do a higher volume of work to get them. The more physically fit and trained your body becomes the harder you have to work to see 200+.
