Don't over think this ride, there are plenty of followers on the route that are supporting riders. Raise your arm and someone will eventually stop for you.

Throw that pump away and get a couple of CO2 inflators, ahhhh, that is why I always give myself new tires for a long ride, lesses the chance of flats but if you hit a chuckhole or tacks or glass, no new tire will help, maybe.

Also make sure your wheels are trued to perfection, makes for a smoother ride, your butt will thank you.
