AM: Good solo workout. Started at 10 AM, very sunny and pretty warm (78 degrees). Pyramid tempo fartlek, 1-2-3-4-5-4-3 minutes on w/ half rest. Mostly around the to-be-named Lake Loop in Wash Park. I was initially worried that there would be a lot of pedestrian traffic on such a nice day, but the crowds were manageable. Tried to start conservatively due to heat. Reps between 5:30 and 5:50 pace, and offs between 6:40 and 6:50. Switched to the roads after the 5' rep. Felt good, but HR was just really high in the warm weather. Felt myself start to get overheated during the last 3' rep and called it there. Then jogged to the track and did 3 100's near max effort w/ running start and about 4' walk rest: 11.4, 11.5, 11.5. Happy with those. Cavus felt good as well.
