Tide sports laundry detergent works great.  Also, try hanging your work-out clothes above the shower or outdoors following the washing machine.  (High heat from the dryer sometimes permanently sets in stains and odors).  I seldom put exercise apparel in the dryer, or only for a few minutes...spray them with Febreze before and after the machine (or hand wash) and let them air dry naturally.  Also, use a strong cream/lotion (one marketed for male althletes) and that will reduce the body odor transferred onto clothing.  Same thing for body wash and deodorant...get a stronger men's version and then do a quick spray of light cologne underneath your arms (Adidas dynamic pulse or something along those lines). 

Do not worry about smelling like a man...unscented versions are available, but honestly, even the harsh aroma of some brands is better than fresh perspiration. 

Hope this helps!

Run it through a regular laundry cycle, then dry as usual, then put your stuff in the freezer for a few hours. The extreme cold will kill ALL bacteria that causes stink...great little trick there, and it won't prematurely wear out your clothes like harsh detergent or high heat.

I put vinegar in a downy ball and add a little bit of eucalyptus oil to the water as the machine is filling., I do this for all my laundry, not just running clothes. If I need to dry my running clothes, I use the low heat cycle. Most things dry on their own overnight but a few items need the dryer especially in the summer humidity.

I wash mine in cold water, with a detergent I make myself (Ivory soap, baking soda, borax, and washing soda). Rinse twice, vinegar in the first rinse, and AIR DRY!! The heat of the dryer sets stains and odors! And this way, I have a shirt I've worn and washed probably 50 times this year and it still looks brand new.

I hand wash my socks to get the dirt out.

Also, consider your diet. Animal fats cause a particular odor in sweat. When I'm on one of my periodic vegan cleanses, my perspiration has almost no odor.

+1 to allowing running clothes to air dry as a preventative measure. I've never had a problem with residual smells (after laundering), probably because I almost always let the clothes air dry. Otherwise they can become breeding grounds for mold and mildew. If I'm at the gym or on travel and have to pack running gear while it's still wet, I put it in its own little laundry bag and then take it out of the bag when I get to my destination. The same applies to running shoes.
