Indoor, I think there are now 34 (17 mens and 17 womens including the relays).
In the past two years we've won 2 mens and 1 womens, second place in 1 mens and 1 womens, third place in 1 mens and 1 womens. We have a guy that's been within inches of winning the high jump the last two years.
We won a couple about 10 years ago, and then you have to go back to the 70s to find another.
