Crazy New Goal

OK so after I found out about Yasso 800s, I told my coach about it and he gave me a workout progression based on 800s. I started running 800s and now I’m doing that at about 3:05-3:19 per 800.
My new (CRAZY) goal: run a marathon in 3 hours. YIKES. But given my 800 times, it looks like I can get close…?
I’m psyched and going for it!
