Well you have a history of marathons - thats good.
I'd probably go for walk run earlier rather than later - but I'm sure you'll get round and under 5 I reckon.
I did VLM this year on no runs over 13 miles (and that was just the one) and did 3.29 despite me attempting to pace for 4.00. But like you I have a fair few marathons in my legs.
Good luck with it.
