Slow ride from hell

This morning I decided that I would make up for lost rides after my injury.  Big misconception on my part.  It was 96℉ at 8:45 AM when I started my ride.  No matter how hard I pushed myself it was like pedaling against a brick wall. My average speed was 10.1 mph and my max speed was 18.6 mph. I burnt 584 calories and my HR was 142 bpm avg while my max HR was 183 bpm. Maybe I should have stayed home today as I was under general anesthesia yesterday for a procedure on my lower back. I just wasn't thinking when I decided to ride.
The trike is working fine after the repairs, just a few things need tweaking, and I will leave that until a cooler day next week.

My riding stats are posted below.
