Ditto this.

I also now use the Forerunner 305. I had the EDGE 305 for my bike and I carried it on a couple of runs, but then it went wonky on me. I got a FR305 for like $125 on Amazon a month or so ago and I love it. Prior to that, I was using a bike computer on the bike and then wearing a regular HR watch/monitor for the whole event to time it and pace myself. The 305 has HR too though, so I only need the one device and so far, it's been great.
