Garmin was playing up throughout the day. By comparing my data with my bro's, we worked out that the Garmin "lost" 13km of my ride. Therefore, total distance should be 183km and average speed should be 25.5km/h.
great ride Matt well done!
Awesome ride ... you'll be well set for the 3 peaks this time around.
Serious action, buddy. Huge day. You're on fire. How hard was the heat!
Check your settings on the Garmin relating to your wheel/tyre size. It makes quite a difference over long distances. Dont set it to automatic. Actual diameters can be found with a quick google search.
