I can get this using my mileage plus points from work travel... worth it?? considering i currently have no computer whatsoever??

My girlfriend is a runner first, cyclist second. She uses the 405, it works but it's not ideal. The good thing is you can get all the same features of an Edge, like altimeter, you can pair with ANT+ devices like cadence sensor.

The downside - the display is small so you won't get the same amount of data you would with a true cycling computer. The touch bezel system isn't easy to use on the bike. The altimeter isn't as accurate as the Edge models. The biggest problem is the lack of battery life, especially when you get ANT+ devices paired. The device rarely lasts past two hours when using cadence sensor and heart rate monitor. It also isn't compatible with power meters.

If you're looking for a dedicated cycling computer, I'd save up for an Edge and use your mileage points for something else. If you run a lot and cycle a little, the 405 would be a good way to go.

ya, that's kinda what I was thinkin... I'd rather get a dedicated cycle puter but can't use my points to get one... oh well... worth asking about

We have the 405 and 310XT (and 305, 705). If you can get the 310XT and the quick release kit it comes with a bike mount so you can use it like a regular computer. GL

Skip the 405, it's the one poor computer that Garmin has released. The touch bezel is terrible for running, and even worse for cycling. I'd pick up a 310XT for versatility and power support, or an Edge 500 for dedicated bike computer-ness

I have the 205 and use it for running and occasional biking. I bought a cheap speedometer for most rides for $11 at walmart, but when I do actual interval training and I want a stop watch, i'll use my garmin

It's not even close to "poor" and I have no problems with it for running (I use autoscroll and avoid any bezel problems). It's been fantastic for running going on a year now. That being said there's no way I'd want to use it for cycling mainly because the screen is too small to hold much of the data I prefer to see on a bike computer.

I have a 405 but I wish i had a 310xt for what its worth

I have the 405 and would not recommend you get it. It's annoying to use for several reasons. For example, when the watch gets moist from sweat it's nearly impossible to use.

The GPS and data are good, but the user interface sucks.
