Regardless of the sport you practice, you probably need to be doing some form of periodization. You can’t go for PRs every session because at some point your body stops being able to recover => you get hurt.
replyYou may want to talk to your doctor about potential exercise-induced cardiac remodeling. Not an expert on this at all. But it’s an injury mode that’s been recently characterized due to sudden deaths among young, seemingly-healthy sprinters.
replyVery interesting. I can also get Afib after many years of high intensity exercise
replyThis happens to me occasionally, but it's typically stimulant and blood sugar related.
replyThere are some indications that it might be related to ion availability in your body, so copper, zinc, and calcium specifically. You may also consider that HF RF found in phones, wifi, and Bluetooth can do not great things to the calcium channels in cell walls (it essentially locks the channels open in some cases).
There are a lot of factors to this, but these are things I've picked up in my reading for my own issues.

reply> FYI I'm in my 40's.
replyBad news: Age is a risk factor for AFIB. The older you get, the more likely it is to happen.
Also a significant increase in AFIB risk for runners. I am doing around 10-20MPW over the last 5 years. Not sure if this is enough training load, but I've had a habit of pushing too hard on my runs as well.
