Has anyone done a Duathlon relay?

My husband and I are doing a duathlon as a team in a few weeks. I'm wondering if anybody has ever done this, and if so, what was your strategy? I'm doing the runs (1.75 mi x 3) and my husband's doing the bikes (11 mi x 2). I'll have about a half hour in between each leg. I'm wondering how hard I should push myself, since I've never had breaks like this before in the middle of a run.

Also, what do I do in between? Stretch? Collapse and take a nap? (lol)

Thanks! Any advice would be helpful!!

anybody??
