The topic came up today and someone suggested (at least in Utah) a way to expand the state meet was to add a heptathalon/pentathalon (maybe with no pole vault) and a 2K steeple.
Currently Utah has the following in all divisions:
4x100, 4x400, 100, 200, 400, 800, 1600, 3200, LJ, HJ, Javelin, Disc, and Shot. (no TJ)
In the larger divisions (4-6A) they run the 4x200 and 4x800.
In the smaller divisions (1-3A) they run the Sprint Medley (2,2,4,8).
Pole Vault doesn't score for the teams but is an exhibition event.
What events would you want to expand high school competition with?
