Higher Heart Rate Racing Cyclocross

Been racing road and cross for 40+ years and last week I noticed my post race heart max and average numbers higher compared to past years.
Previous years:
Max - 170
Average - 166
Last 2 Races:
Max - 177 - 184
Average - 171

At my age (65) I’m starting to wonder if racing cross at “Redline” is something that I should reconsider or am I fitter this year and keep on going?
I have no ill effects post race with exception of the usual post race fatigue as expected.

If you’re not feeling any negative effects, I probably wouldn’t worry about it! HR can vary because of many factors – even year-to-year.

If you’re concerned, though, we’d recommend talking to a doctor about it.

My heart rate is higher when I race cross too. My avg for a 1 hr race is typically 186ish (i’m 17), but my last cross race my average was 192! My max also tied my all time max of 206.

Watching some of the ‘cross’ races I’ve seen on tv, I can believe they would induce a higher heart rate in participants. Wow…

All my CX races had my heart beating out of my chest.

That’s a 1hr cross race in 2022, average 179 for an hour, my max HR at that time was 193! I got a similar result last year on the same course, but at a slightly lower average HR (176). It could be that you’re fitter, or the opposite, that you had to work harder for a similar effort/result.
