Just looking for some insight as to my HR when biking and running. 51yo, male, 5'10" 170lbs, been doing this for a couple years, train about 10 to 12 hours week.
When I run at what I feel is a moderate pace my HR is around 160, which is around an 8min mile, I can go 10 miles at this pace and usually do once a week, to go much faster, say a 7:45 pace my HR usually goes around 172-175, this is high effort for me.
For biking my FTP is 247, my HR is much lower on the bike but the effort level feels high, for example, 1 hour plus at 200 watts average my HR is 130-135 but the effort level is high similar to running around an 8 minute mile. A more comfortable 175 watt average power my HR is 5-10 beats slower but the effort level feels more comfortable and sustainable for longer distances.
I would suspect I need to work a little more on the bike, not sure there is much room for improvement on the run. Recently did a HIM just under 5:40, which I was happy with, did IMMD last year where the swim was cancelled, the bike was shortened and the run was a disaster with the flooded course, finished it in around 11:20 but didn't put much effort in the run due to conditions.
Thanks for any feedback.
