Here's the Garmin stats for what was probably my hilliest day, from Kilkenny to Dublin through the Wicklow mountains in Southern Ireland. Just over 10000 feet of climbing in just short of 130 miles. As you can see, I didn't exactly break the land speed record but as this was the final day of a four-day, 500 mile tour I feel I have an excuse. LOL
Oh, and ignore the calorie count. The Garmin 305 overstated calorie consumption by a factor of about two.
