Getting old but not past it

Simple answer: NO. I think you are being very optimistic to keep a 15mph average speed, unless you are super fit and well trained. But I would be happy for you to prove me wrong.
A few years ago after recently getting into road bikes I was an approaching 40 year old ex smoker who winced at the thought of 'training' (still do, I just ride my bike everywhere, I don't train, training is for the kind of person who would go to a gym, I'm not one of those people). I'd done a couple of centuries but wanted to try a solo 200 miles during daylight hours. I did it at the end of May and left after sunrise about 4.30am, I had a ruksak (not recommended for long rides) nearly as heavy as my steel bike, well over 3 hours worth of stops including a full pub lunch, so I was enjoying it not hammering it. Riding time was 13 hours and I managed just over 210 miles before dark. It was hard but brilliant fun, and I'm still boring people with it now

, and the end of April is still 5 months away, so you should be able to get some decent miles in.

Total Miles= 166.6
Average Speed 15mph = 11hrs 8min cycle time (excl stops)
Working on basis you have 5-10min snack stop every hour (fluids / energy) and 15-20min break every 3rd hour for carb snack
8x 10min breaks
X3 20min breaks
2hrs 20mins
Total journey time:
13.5hrs
Depart- 06:00
Arrive - 19:30
Easily do-able in a day, with the right training. I would start earlier than 6am though - you need to give yourself as much time as possible.
What equation are you using to determine that you will not get any delays due to punctures etc as I notice you have not given any time to the possibility of mechanicals or people coming off?
They dont have much daylight to play with.
Easter Sunday is 20th April,
Sunrise 05.55hrs - sunset 20.05hrs
But probably only because I could never do it. Took me and another cyclist 12 hours to do a fairly flat 102 miles, no punctures, Strava had me at a moving average of 13-14 mph. I was pretty saddle sore by the end, could barely sit down for the last couple of miles

. Moving on, people have mentioned physical but for a ride of this length you will also need to condition the mind. I thinking prior training is a must

About 2 hours should do it.
