Is there a good substitute to running 10 miles?

I know running can be a great way to lose weight and get ripped, but is there a good substitute to running 10 miles? For instance, what if I ran five miles, swam a little bit (I’m not a good swimmer, so not very much,) rode my bike for a while, and played basketball? I would do these all within a short period of time. What would be good distances for each sport to get similar results to running 10 miles?

How do I improve my endurance when running?

What are the best sources of information on how to select and buy the right road bike for triathlon use?

I am a serious age group athlete generally finishing in the top 20% of my group. Even after several years of competing I still feel seriously ignorant about bikes. I know I need a new one, but I don’t know where to start with research etc. My top priorities are FIT (my current bike never fit properly and holds me back) and, ease of use (maintenance, tire changing). Yes, this is important to me. The amount of info out there is overwhelming so advice on where to start, what questions to ask, what to read, etc. is very welcome. I do Olympic and half Ironman distances but will work up to my first full IM in ’07 or ’08. So new, good bike is critical. Thanks.

Did I officially do an ironman triathlon even though I went over time limit?

I did an ironman distance triathlon last weekend. All the distances were exactly the same and the same rules applied (no drafting,etc.) However, this was not an officially sanctioned ironman event. As such they let competitors go beyond the standard 17 hour time limit to finish. I finished in about 17:30.

My question is should I put a 140.6 sticker on my car? After all, I did do every bit of the 140.6 miles.
