Need to have your phone with you: http://www8.garmin.com/livetrack/

IT has a feature called Virtual Partner where you can set a pace you want to stay on, but don’t think you can plug in a time. It’s also a bit of a risk in a marathon since you will typically run a bit longer than 26.2 unless you hit the tangents perfectly, so for pace you typically need to go a little lower than target pace.

I’m thinking about getting the garmin forerunner 620 I have one question on the watch can you plug in a time you won’t for a marathon and will the watch tell you to speed up or slow down to get to that time

I don’t have the 220 (620 for me), but I’d recommend checking out the forums on the Garmin site for a solution. Lots of troubleshooting there, and I know a bunch of software updates have come out for the 620.

Thanks!

If 12+ hrs is critical, I’d go for watch made for that kind of life – Garmin Fenix, Ambit, 9100xt

Thanks for the detailed review, need to work on my own!

As for setup on the watch, I found it to be very intuitive, and once set, I could leave it be after my 1st run and making adjustments. It allows you to display the data on up to 5 separate screens that you can select to scroll through on its own, or you can manually swipe to the screen for the data you want to see. It is a lot of data to try and analyze when you are running, so I suggest keeping the screens simple. Each screen is preset to what data you can display, but you can display 1 or up to 5 data fields, but it makes it a bit hard to read when 5 are displayed.

Vertical Oscillation & Ground Contact Time seem to be neat features, but GCT I can’t see changing unless you change other items, so it becomes more novel of a data field. Vertical Osc you can help try to change without having to try and change a lot of other areas of your form. I do try and keep my bounce down, but again like GCT sometimes you can’t help it much.

What I really like is the Garmin Connect website. It shows you all your data in pretty much any format you may need, from graphs to replaying the data on the map. This allows you to analyze your data after the fact instead of while on the run. I can see where my HR increases or my stride changes due to the course and elevation change.

As for the VOX, it only shows on the main page and it is an overall measurement based on all your runs. It does seem to coincide with improved HR stats on my runs over the past weeks. The recovery report only shows on the watch itself and not on Garmin connect. It also seems to report pretty close to how I am feeling after the run. If I felt good after the run and I confirm it by the data, it shows a shorter recovery time. If I felt like I was having a hard time and my HR shows higher than normal, it shows a longer Recovery time.

As for the APP, I use Android, so it does not sync up for live track yet like the iPhone App. The other thing I have noticed is that you can only see basic data of your runs like HR, pace, time, elevation, & avg Cadence (but it seems to report only 50% values). I have heard the app is to be updated sometime this January for Android, but I am not holding my breath.

I hope this helps answer some questions. I have only been using it for a few weeks now, and I am going off memory so some of my statements may be a little off (like number of screens).

I’m hoping to get a 620 soon, so we’ll see.
