I have 4 months for training ultra, if you have mandatory thing i need to know for performing correctly

I know this probably isn’t the place for this kind of post but i really need some advice. Recently i have been struggling doing the thing i love which is running due to the fact that normal heart palpitations cause me to start worrying that something is wrong with me and i get into this loop of anxiety which tenses my neck muscles, temples and overall i don’t feel very pleasant. If anyone has had something similar happen or has dealt with something similar can i get some advice on how to deal with it. I also know that nothing is wrong with my heart ive recently done a 100k ultra w significant gain so something should have happened if something is wrong.

Anyone ever summit this old baldy in lewistown Montana?

Strava shows a trail for 1.5 miles…

What’s the best awards you’ve gotten from a race? Particularly top placements or random awards (like exactly middle of the pack award). Which race and upload a photo if you can! Would be fun to see who’s got the cool bling!
