landscapes and triathlons

Those two things really have nothing in common except they are occupying my mind right now.

We are looking for a landscape architect to help with some big picture stuff in our yard. Anybody out there used one or know one you would recommend?

As for the triathlon topic, I am thinking about doing a mini-triathlon as my next adventure. Has anyone done one? What tips might you have to get started. I have done a bit of research on the web, but a first person account is much better. When I started running I talked to Rodney W. so much and learned more from him than anywhere--and we still talk about running! So, what advice do you have for me?

Thanks for your time and I look forward to your comments!
