Great North Bike Ride Advice?

[Serynia]

Thinking of doing this in August, probably going to be about 9 in a group from my work. Just wanted to know if anyone here has done this ride before and how doable is it for your average cyclist?
I have gotten back into cycling a few months ago and am currently up to about 30 miles, I struggle to find the time to do more sometimes, luckily I have another two weeks off work to train for this. Hills are still my nemesis although they are getting easier and my new bike certainly helps. Anyone done this ride before? are there any sections I should be aware of ? or m I just nuts to even try this?

As it's a ride down the coast, it's mostly very flat. Depends on your abilities obvs, but I've seen lots of "average cyclists" doing it. I haven’t done the actual ride, but I know the route well.
