I agree with Joe Daly and Charles V that the average runs/hr at Maxton was 40. I expect the run logistics to be the same as the short turnout is the same 1.4 mi while the long turnout is 1000ft shorter if 9000ft compared with 1.9 mi (10,032). I would expect the drivers meeting to be much longer the first day but I would hope they will take that into account and start it at 0800 instead of 0830 so we can start at 0900.
Now if those assumptions are true then the only potential problems will be all the newbies being ready to run as they get to the front of the line. That is where those of us who have run for several yrs can truly help by seeing and advising newbies on any timing issues as soon as we notice them.
Then the "turnaround time" assuming the 175 entries fill, show up, and all are ready and in line (which will never happen in my experience) then I would assume the best time would be 4 hrs 22 min 30 sec...
40 Runs per hour, 175/40=4.375 hrs for a full cycle.
14.5 Hours Total Run time. Saturday 9:00 to 6:00 with 30 min lunch break = 8.5 hours Sunday 8:00 to 2:00 = 6 hours
14.5x40=580 Total Runs, so if everyone was always in line then 3.3 runs/ entry.
So Garrell your plan will require 2 meets. But so what? Have fun. Check out all the other peoples cool toys and fascinating solutions to speed problems. Bring a small camera.
