30 Miles Single Speed Plan

I am going to attempt a 30 mile bike ride tonight on my single speed. Never gone that far before. Checkout the map below of the projected path.

Start and end at the little house icon. Red path is stage 1, green is stage 2, and purple is stage 3. This takes me from the west side all the way downtown and back. I figured out a path that did not track back on itself. I am trying to stay on the paved paths around town as much as possible.

I marked this out on Google Maps by hand and it comes to 26.92 miles. Hope in the final tally puts me at 30 miles. Barring any mechanical issues (which are entirely possible on the bike I am riding), any physical breakdowns (which is also possible with my depreciating body), or any crazy acts of nature I think I am going to be pretty tired tonight.
