I don't think warping would be allowed, this is intended as a grinding event.
I think what he's proposing is this: all participants roll the same race, and await a starting signal, then they grind to 60. No warps, no support from other alts or other players, just simply a race to lvl 60 through quests/kills exp. This has definite potential as an event. We could do this for each starting area on a rotational basis. We need an idea of how long it would take to get to 60 without warping or using alt support. If its as long as I think it would be, the rewards should be a bit bigger then a hide and seek type event. I think winners should be determined by screenshots of /played time in the event of a close race, as this will give us an accurate answer to the time taken to level.
