THINK! tHNK ABOUT WHAT YOU'RE TRYIN' TO DO TO ME!
Sorry, kinda had to be done.

I can ride 75 miles on my single but it would take me about 7 hours with stops. Are you really thinking of doing 150 in one day? In order to do it in one day and stay in the light, if you rode on the one day of the year that there is 12 hours of daylight you would have to average 12.5mph. Not saying that is a lot, but that's the one day with 12 hours of light.
To do it in 10 hours, with no stops, you'd have to average 15mph. Again not saying that's fast, but that is with no stops.
I'm thinking that this might be a bit much to do in one day and be able to walk the next.
I know some people who can do 150 miles in a day in 8 hours but they average 20 mph and are able to stop along the way. They're racers.

Good luck in whatever you decide.
