Every athlete is different as far as what they like and tools they use. However, first I’d like to support your intuition. The fact that you foam rolled for the first time in 11 weeks and went big the night before could have easily been a trigger for the problems hiking the next day. Any deep work, rolling, massage, PT, chiropractic self care or acupuncture ( ; should have 24 hrs rest afterward. So next time do it before a recovery day. Or do very light work after a hike though I prefer gentle stretching post activity to foam rolling.
I don’t foam roll much, I use it on recovery days to target troublesome areas, either a massage ball or a roller. I am a big fan of light cupping work myself on larger areas. I also do monthly massage/PT and chiropractic to balance it out. All done with 24hrs of recovery planned in afterward.
It’s not a getting older thing it’s just getting smarter ( :
As for the HR chest strap. Yes this is all chest straps. Think of it this way, anything that has any form of transmitting capability has the potential to interfere with a beacon in both send and receive mode. That’s why the rule is phone off, no chest strap, and anything that can transmit carried a full meter away from your beacon. So if beacon is in pants pocket, everything else should be up in the top of your pack. If you want to snap pics with your phone, take the time to turn it on and off is most ideal unless you are traveling in a zero risk zone. Were your HR chest strap for everything else you do, you will develop “the feel” for being aerobic over time. It’s a great practice anyway. Then go by feel when touring and have accurate chest strap data for other aerobic activities.
I hope this helps!
