Garmin Rides High With Winning Tour de France Team

Good article from last week's Kansas City Star newspaper discussing Garmin's sponsorship of pro cycling:

The Olathe-based manufacturer of GPS devices is the title sponsor for Garmin-Cervélo, a cycling team competing in the Tour de France. On Sunday it won its first Tour de France stage victory in the team time trial. Tyler Farrar won the next stage, becoming the first American to ever win on July 4 and the first to win any Tour stage since 2007.

Teammate Thor Hushovd has held onto the overall lead, and the leader’s yellow jersey, four days into the three-week race.

Sponsoring a pro cycling team can cost millions of dollars. Jake Jacobson, social media manager for Garmin, said the company had spent a large amount sponsoring the team, although it wouldn’t release the exact figure.

Barometric and Digital Elevation Model (DEM) Correction with Cycling Running Skating Global Positioning System (GPS) Data

Congrats to all who are spending plenty of time exercising! Kudos if you do that AND spend lots of time thinking about this while exercising or not. Thinking about exercising is part of actually going to exercise. And any mind game that gets me out exercising is a mind game I like. Also, thinking about scientific and mathematical issues keeps brains exercised along with the rest of the body. If you feel elevation data is irrelevant to your training, you won't want to waste your time reading this article. If reviewing your data informs you and inspires you, read on to see if you agree.

Inline Speedometer Recommendations? Replies by Actual Users Discuss and Review Forerunner 305 HRM GPS

As previously noted, at A2A I was totally unprepared for the scathing speeds most experienced racers attain. I'll do A2A again if I think i can do it sub-6 hours...But I need to know what that speed feels like, and how to work to generated it.

I recently found (duh....) that there are indeed inline speedometers, some of which combine with heartrate monitors. Any recommendations as far as good deals, reliability, and durability go?

How to Reboot a Garmin Forerunner 305 That Locked Up When Recharging on the Cradle and Won't Power On

The Garmin Forerunner 305 is great. Despite a few weaknesses (calorie count, altitude), it is a great value for anyone who will use the information it provides. It's the best training tool I know of. But on the big day when you want to do an event, it is possible you won't be able to use it (until you read the reset method here). My Forerunner 305 has on several occasions after recharging on the cradle in various situations (charge by AC, charge by laptop USB, charge in the car using a USB cigarette lighter adapter) refused to start.

How to Report an Error (Mistake, Bug) in Google Maps Navteq or Teleatlus Data

While working on development of a route I have been using mapmyride.com and have found it very useful, but when it comes to a left off of Vernon Rd onto Sandy Cross Rd to get to the store at Sandy Cross (upon the location of which Google, Yahoo and Mapquest seem not to agree), everything goes hayougetoffomycloudwire. Part of the road is missing from the map overlay, but it's clearly visible in the satellite view (though in some sat views I can see the road blocks from some previous construction destruction.

A2A 55-mile skate -- Sunday morning fun skate went out of control

The Texas Flyers had planned to send a team to 2005 A2A [which was canceled that year --roadskater].  I wanted to participate in the worst way.  I was too weak to skate at the time and started to ask skaters to go to A2A.  “Don’t wait ‘til you’re ready.  Go while the event exists.”

Athens to Atlanta Roadskate (A2A Skate): Total Ascent, Elevation Gain; Barometric or GPS Data?

Does anybody have the total ascent or elevation gain for the 87 mile Athens-to-Atlanta (A2A) course kicking around somewhere in their GPS or training files? I have googled all sorts of term combos, as well as searched this site. Blake's A2A mapmyride entry shows highest & lowest elevation but doesn't add it up for me :-). I'm feeling a bit fuzzy headed today so it's entirely possible I overlooked it, but please post that figure if you have it!

Watch Tour de Georgia Cycling Video and GPS Tracking Free Online

Wow. Really great stuff and sorry to be late on this with the Eddy workshop and guests coming to town, but over time, free internet video and the Tour de Georgia are both getting cooler. As I had to keep telling myself last weekend, I can't leave town right now with lots to do and some of it requiring me to be here, so I will have to enjoy this opportunity from afar it seems. If anyone thinks they want to get a carpool together later in the week, let me know (I know I'm dreamin').

Garmin Forerunner 305 GPS Heart Rate Monitor has a Useless Calorie Counting Feature

If you're in the market for a heart rate monitor and place great value on the calorie counter function, I would not recommend you buy a Garmin Forerunner 305.
