Thinking about running around the course watching the leaders. Looks to me like the race could easily be viewed at 1-3-13-17-20-25+ (actually without much running)
Start out the race at 1, run over to 3 before the leaders get there to get on the inside of the course, walk over to 13.1, walk to 17 then 20, jog back to Roosevelt road to catch them at 26.
Any other advice to watching the race on the course?
