Endure and persist; this pain will turn to your good. - Ovid

Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ, through whom we have gained access by faith into this grace in which we now stand. And we rejoice in the hope of the glory of God. Not only so, but we also rejoice in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope. And hope does not disappoint us, because God has poured out his love into our hearts by the Holy Spirit, whom he has given us. - Romans 5:1-5

Day off. I have done some work on my new "Marathons and Maps" blog, so check out the updates. Most of the blog entries up to this point are updated off of this blog, but I've done some text edits and added some pictures and hyperlinks where appropriate. I've also linked the blog with Feedburner, so people can "subscribe" using RSS feeds, and receive the blog in their email or favorite news reader. Once I get the backlog from the fastrunning blog on there, I will start writing new entries.

Paul, with your GIS/Cartography background, you must have an opinion on the Garmin 205/305. Do you think they are accurate in most conditions or do they have a limited range of conditions in which they work well?

From Paul Petersen on Thu, Dec 14, 2006 at 15:52:07

Mike, I have never used a Garmin 205/305, but GPS is an interest of mine. Some things are true of GPS units regardless of model. There are 4 basic grades of GPS: recreation grade (~15m accuracy), mapping grade (1-5m accuracy), high-end mapping grade (sub-meter), and RTK survey grade (

RTK

Forget it, the blog is broken.

Stay away from trees, cliffs, and clouds and the gps will be fine. The more sky the better.

okay, the orignal response came to my email at least, so let's try copy and paste:

Sasha, your blog has issues!

From Cody on Thu, Dec 14, 2006 at 19:54:36

Mike and Paul,

If I can put in my two cents...

I have been using a Garmin 305 (using "High sensitivity SiRFstarIII architecture") for just over a week so far so I don't have a lot of experience with it yet but these are my initial findings.

It seems to be accurate to within about 30 feet. The mile locations that I measured on my bike are within a few feet of what the Garmin shows for a mile.

The printed specs (which generally mean nothing) say that it is accurate to < 10 meters (Position). It also states it is accurate to < 0.05 m/s depending on a clear sky (99% accurate on clear sky, 95% - typical).

However, I have observed that the lap times are accurate (per mile), but my current pace is all over the place (plus/minus 20 seconds/mile). I also noticed that the elevation and grade features are pretty much like the pace feature....All over the place. It shows a flat run (around 40 feet elevation change over 8 miles) reporting a 250 feet up and 250 feet down change. So I pretty much have to disregard most of that information.

All of that aside, I love it because I am a techie nerd type (Engineer).

Enough said-

From Paul Petersen on Fri, Dec 15, 2006 at 04:59:31

Oh yeah, I never mentioned vertical. Rec-grade GPS's are TERRIBLE with their z measurement (elevation). Elevations will be all over the place and CANNOT be trusted at ALL in ANY situation. If you are ascending or descending a lot, there will be a substantial "lag time". So Cody's observation is consistent with that.

The longer so sit on a point, the better satellite fix, and the more accurate the point will be (lat, long, and elevation). The problem is that runners are always moving.

From Mike on Fri, Dec 15, 2006 at 05:43:21

So I should invest in a GPS watch if I want to stay in one place. It doesn't sound any better than if I run with a Polar 625X. I have one of those and the pace feature doesn't work well enough to use it for speed work. 20 seconds per mile is a lot when you are trying to do a tempo workout.

From sp on Fri, Dec 15, 2006 at 06:25:36

Mike:

Garmin 305 is quite useful for speedwork. It is usually very accurate, but once in a while is wrong, and sometimes very wrong. If you run the same course 10 times and average out the measurements throwing out the off-the-wall ones, you have a 99% chance of getting USATF certified length. However, do not trust the elevation and the immediate speed.

From Paul Petersen on Fri, Dec 15, 2006 at 07:34:20

Agreeing with Sasha, all the feedback I've heard on the 305 is that it is pretty accurate for things like tempo run splits. I used my Garmin Foretrex to measure the TOU course, which has certified mile markers that are pretty reliable. Virtually all my gps mile marks were within +/-0.01 of the certified miles, so within about 15 meters, which translates to about 3-second error at marathon pace. The Foretrex gave me a differential fix, so was better than the old Forerunners, but is probably equivalent to the newer Forerunners. Keep in mind that reception up Blacksmith Fork will not be as good as in a low-topography area, plus tangents come into play. But I think +/-3 second per mile error MAX is a pretty safe assumption for anywhere with a decent fix.
