The guy that did the lands end to john o'groats planned every detail over something like 6 months or more and even fitted a larger fuel tank to limit fuel stops. Even with all that planning I think he was extremely lucky to pull it off. Trying to do it on the M25, although it's a much shorter distance, I think would be near impossible purely because of the location and the technology on that stretch of road.
However, I'm sure there are some people out there who would be stupid enough to try.

Again, having said all that - easter sunday on lockdown is surely the best opportunity to give it a try
