Excellent, Slugger! If today was a "long bike ride" day for you - you totally should have joined us for a C-ride with the shop today. We gratefully got dropped off the back and 6 of us did our ride at our own pace and had a grand time.
As for running, Saturday I did "speed work" at the local HS track. Except, the track team was practicing when I got there (

) so I did my intervals around the football field (which the HS athletic director had recommended when I contacted him about using the track in the first place). But...after a few days of rain, the edge of the field was slick mud, so the footing was less then sure and it was a VERY challenging set of intervals.
I think I attached the file from the workout. It shows just HOW small a football field is compared to a track. I had no idea, but suspected something was up, as I had to run 2 2/3 trips around the field to get my 1/2 mile interval in, vs. 2 laps on the track.
Saturday is my first official duathlon. I hope I'm ready. I really want to get one more run-bike-run workout in with my tri club on Wednesday. After that...it's "either I do it or I don't" - and I think I will...I just don't think I'll be setting any records.
