Compression Shorts

I need a pair of compression cycling shorts, any suggestions. There a are lots of running shorts, that look great but then there is no chamois. Has anyone bought/found a seperate chamois and then used it with running shorts. The TE sight has great stuff but I really need to order today.I have a pulled groin muscle and have a 7 day ride coming up, so I need to try to get this taken care of quickly. THANKS

I'm confused...are you looking for something you can run and bike in? Tri shorts would fit that bill.

Sorry I wasn't clear, I'm looking for something to ride in, but it wasn't sure if tri shorts would work. Thanks for the information, now I know they will.
