This was one of the main reason I purchased this item -- it be able to have a reliable pace reading.

Loses one star for poor pace calculation during runs- steady pace can show variance up to 1:30.

I understand a smoothed algo, but any watch should be able to develop a reliable pace within 1/4 mile or less.

You have to scroll through the windows as you are running for your time, pace, mileage etc, not real user friendly

I give it four stars because I have waited over five minutes on my busy downtown block to get a satellite signal (trees?) and it never syncs up to the right pace on a treadmill despite treadmill mode (however, you can calibrate it afterward so no big deal), but otherwise no problems not even on trails and remote areas

When I run I have the distance as the big number, the average pace on the top left, and the total duration on the top right and it works perfectly

In other words, ALL the graphs added on the distance and time I traveled/rested while in paused mode, although the top line workout summary (pace/distance) did not.

When the pace reads slow, and I speed up my pace, it takes several seconds to minutes to register that the pace has increased and usually says I'm going slower before it says I'm going faster.

Loses one star for poor pace calculation during runs- steady pace can show variance up to 1:30.

Of course this meant that my average pace was dramatically slowed because the watch insisted that I ran .6 of a mile less than I actually did

They are fast and the pace in particular is non responsive, even when walking my pace is about 8 minute mile

Seeing your pace isn't as helpful.- Lap mode: Manual lap mode makes up for many of shortcomings of interval mode

They sent a new one with a working joystick and what appears to be a more reliable pace calculator

I also noted, that, although the distance/pace top line are not affected, even the graph of your route has this paused distance added on, as where the route traveled showed I crossed the 3 mile point was NOT the same point that I actually crossed 3 miles.

I only use it occasionally, especially to support pacing during racing, but I love the simplicity of the design, how easy it is to see the numbers during a workout and the Quick GPS (only remember- if you haven't used it in a few weeks, it takes sometime to find the GPS).I'm writing the review because I just tried out the RACE feature on the watch for the first time and I loved it!!!

(it goes to a slower pace, so I know it's not just starting a new minute).3.

Mile 2 it got right, and then it proceeded to UNDERestimate my pace for miles 3-5.

so I took the watch for the same run on my local gym's treadmill and got the same discrepancy where according to the watch I ran over 4 miles at a great (fgor me) pace but per the treadmill I was again averaging about a 10 min/mile pace.

:) Works just as i have expected, really awesome buy :):)

I used it indoors as well as

I was able to set it up so that when I do that, the data goes to the TomTom website as well as to Strava automatically
