ooooof!

Wanted to run today since it is a holiday and I'm posing as a runner. Went out at the hottest time of day and  picked the busiest Phoenix afternoon roads to run on. I wanted to run out in the open water so I chose the Camelback road from 20th street to 32nd street thing and make it a tempo run. Lot's of construction, lots of cars, lots of people offering to call the paramedics for me. But I got in 5 miles and at a decent pace. My HR went high right away which alarmed me so I tried to slow down then got messed up on pace. Never fell into a rhythm pace-wise but the Garmin results show a smoother workout than it felt. Here is the Trailrunner data:

I've been reading a lot of Tri blogs and wondering if I can ever get to that level. Just wondering......
