Ours was 43km. 4-5k longer than you and Ben. How much do you estimate to get the ones you missed?
#47 - 960m
#22 - 3000m
#33/#39/#41 - 1800m
In retrospect, grabbing 41 enroute to Nemo from 48 would have been better than saving it for the run in.
About 5700m, though near #34 we got boxed by chain link and worked N, and then more fencing issues getting to the cloverleaf so I think a more efficient route transitioning from the northeast to the southeast maps might have saved a km or so
Our route was 34-37-30-29-31-32-35 but a better route may have been 34-33-32-31-30-29 (out to Knox Marsh Rd) 37-35
Looking at Ben's map, I didn't realize 22 was as close to 21 as it was, would have made a lot of sense to hop off the first map to grab it before heading west.
