A Very Good Running Watch
My Forerunner 45 was no longer holding its charge through a full marathon, so I updated to the Forerunner 55. It has everything I need to train at an affordable price. You can get more bells and whistles in a higher grade, pricier model, but if you don't need it, this garmin will do fine: I have it set up to give heart rate, current pace, distance, overall pace, and in lap distance and in lap pace. I have to look at options to see if there is an elevation ascent widget I can add in. My next marathon has more climbing profile than my typical marathon, so I'm trying to train to specific uphill needs.

Exceedingly functional watch for the price. Everything you need to track a standard run/ride/hike-type workout.

Easy to use and very accurate.
I bought this to do a 10k in my city. It was very helpful in getting an accurate times for my run. Which I spent a bit more money for the overall upgrade variant.
