14 miles, 268m ascent, average 16.2 mph

That's better - got the average speed up a bit at last in a ride up to Mortonhall, then down to Holyrood and round Arthurs Seat.  Worked hard all the way (inspired by watching Cav win stage 5 of the Tour de France), and managed to get cramp in both calves at one point, but soldiered through.

After chatting with Dave at the weekend, I've concluded I need to get much more technical about this whole affair, so I'm now starting to track my heart rate along with the other stats, so that I can get a feel for the level I should be working when I finally do the Fred Whitton.  This ride had my average up at 163, in zone 4 for 73% of the time.  Helen tells me that the TdF riders cruise with a heart rate of around 130 - I only dipped that low twice, probably at traffic lights.

The stats in the subject were from my GPS - the bikeroutetoaster equivalents are 14.1 miles, and 265m ascent.  Amazingly close, but I'll try to track both where possible so that I'm not training based on the GPS stats, for a ride that I've planned using bikeroutetoaster.
