woah!
Found a cool app....
records everything, speed altitude, total level change...
check it out... (sorry for the crap picture, it was the pad taking a pic of the phone display)
btw, this was a day with my kids, the 78km/h was with my 9 year old - he was well stoked. Me too for that matter as I've never had a reading on speed. I'm sure though without the kids I could top 100....
34.6km though covered in a day with a 9 and 6 yr old isn't bad!
