GPiSsed

My mother-in-law is visiting right now, and she asked if I’ve been using the Garmin Edge 205 she sent me for Christmas. I told her I don’t fully understand all the things it can do, because I mostly use it just to put squiggly lines on Google Earth photos so that I can see where I've ridden.

This image of Potter Valley Road is a good example. The road is very popular with local cyclists who climb it—often several times in a single session—for springtime workouts. I’ve been riding it quite a bit this year, so one night a couple of weeks ago, I reset the 205 at the bottom of the hill and then stopped it at the end of the pavement so I could get all the pertinent numbers on the climb.

I can gasp my way up this climb in a little less than 14 minutes (way slower than the people who actually race up it). It is 1.89 miles from the bottom to the top, which involves 621 feet of elevation gain. The grades run as steep as 11 percent. I know this because I was dumb enough to include that information among the fields of data displayed on the screen.

I’m still not sure if there is any good reason to know, at the moment one is grinding up an 11-percent grade, that the hill is actually that steep. It can sort of make a person want to head-butt his bike computer with his helmet. I don’t dare try this, of course, because in my oxygen-deprived state I’d be more likely to slam into my stem and suffer disfiguring facial trauma.

But it sure makes a neat squiggly line on the satellite photo, though, doesn’t it?

The ride down is totally worth the climb!

i have the 305 that has the heart rate monitor on it if you wanna see some neat numbers along with the % incline.

so how did you get that to look so neat on google earth?

Amber, I don't think my heart-rate numbers would fall into the category of "neat."

When I'm climbing Potter Valley Road, they'd be more in the category of "Call 9-1-1."

Some thoughts..

1) Your mother in law bought you the Garmin? Lucky! After 6 years of riding I'm still waiting for my first cycling present from anybody.

2) Dont beat yourself up on the lack of full use of the Garmin. I also have the 205 and you are light years ahead of most.

I have a Garmin etrex venture, which I can't use. I really hate it.
