No your right Lise- It's "splits" as in "my run split suffered because I hammered on the bike leg"... So I guess it's "legs" and "splits"...
But at least if you "tri" as well, they will know exactly what you say when you say "I have to get out of here on time cause I"m doing a long brick tonight"..
The first time I said that to a coworker she thought I mean't drugs!!!
Good luck w/ the job, hope you get it!
