So
the verdict is in and the resounding calls for "no support crew required" have taken the day; besides the comments to the post, I got a few emails along the same lines. It's no surprise when you consider the responses all come from racers, and why would a racer want a support crew if given the option? Unless you're very local to a race, finding a support crew is too often a hassle that prevents racers from racing.
How about an adventure race that makes support crew optional? We've done this a few times in the past and pulled it off thanks to some careful planning and very reliable volunteers. My question is, is it fair to group teams with no support crew into the same race category as teams with a crew? Out in Moab last year, the poor souls who raced unsupported nearly all gave up when they ran out of dry clothes to change into (that was the race where the Moab desert saw more cold and rain than Seattle); our support crew distributed left over hot pizza to a few unsupported teams . . . needless to say, they were overjoyed to have the tasty and hot calories!
Bare in mind that I'm the guy who groups teams of 3 people (coed) into the same race category as teams of 4 people (coed), so my inclination is to group everyone together into the same race category. Sometimes 3 is better than 4, sometimes not; regardless, lumping them together makes life easier for a race organization and makes for some fun race strategy.
Would people feel differently if they were racing for a cash prize of $2,000? Does that change the answer to any of the above questions? In the end, it's our race and we can make the rules . . . but I'm interested to hear some other opinions.
