Today's ride was 6:15 in duration. Just over 100 miles so a little slow but it was 94 degrees and quite windy when I finished. I'm basically trying to find the kind of effort that will allow me to cover 508 miles in essentially one shot. Seems to be in the 120-150 watt range. I'm going to start posting my power files now that rides are starting to get significant. next week 7 hours!
