Odds are this doesn't work too well with biking right?
There are much better options for cycling, although they can be way more expensive on the high end.
Check out the garmin edge, it monitors heart rate, cadence and speed, as well as giving you a map of your routes.

Expensive, but totally awesome.
You can get cycle computer ranging from just speed and distance (you can get these low end models for like 10 bucks at walmart), to speed distance and cadence, to heart rate monitoring, to gps tracking, and anything in between. You can even get power meters that tell you exactly how much power you are generating, though they are very expensive, and way above your needs unless you are training for racing.
I do recommend you get at least cadence and heart rate, as speed and distance don't always mean much for training purposes, being able to hold your cadence and heart rate in the range where you get the most benefit is very useful.
The GPS tracking models make it really easy to compare your rides to see where you are improving or where you need to improve, but they can be a bit of an investment. With the gps tracking you can align your rides by the map instead of by time, so you can see exactly the effect that giant hill has on your heart rate and cadence, instead of having to guess.
