Sportlegs help your body process lactic acid. I tried them for the first time this weekend and they definitely made a difference in the way I felt while I rode multiple loops at the Outdoor Demo.
I love Emergen-C. I have a box at home and now I have a bunch to get me through Interbike. Emergen-C keeps me going when I'm buring the candle at both ends. The had samples to try at the Outdoor Demo and a bin for people to grab some to go.
