I'm 50, run a bit, usually 5k, cycle a bit more. Quite a lot of that on an ebike. But I do push hard most of the time.

Heart rate during 5k's is generally 140-160 depending on how hard I push.

Heart rate on a non e-bike ride 130-150 generally

Heart rate on an ebike ride 110-130 generally, sometimes higher if I push really hard.

Yesterday morning I ran 10 miles "easy" on a treadmill, heart rate was 110-130 the whole run. I rarely run more than 5k or 10k so was pretty proud of myself! Felt good but tired afterwards. Zonked by 9pm and went to bed.

Woke up today tired but ok.

Rode the e-bike this morning to work fairly gently and my heart rate instantly went to 120 and then sat around 135-145 mostly, the odd spike to 150/160 and even 170. I was taking it really easy!

I get my HR from my Garmin Fenix, usually fairly consistent so I think i trust it.

Is this normal? Is my body trying to fix itself from that run? Any reason to worry?
