This is one of those races that I do pretty much every year. It's just a great race - awesome course on the parade route (for Pioneer Day - aka Pie 'n' Beer day to the less-reverent among us) with lots of downhill and lots of spectators. At left, with my friend Leah from the Wasatch Walkers before the race.
The race was smaller this year - they offered a 1/2 marathon, which attracted people away from the 10K I think. I was NOT ready to do a 1/2 marathon, so the 10K was just right for me. I enjoyed the usual runner comments and spectators cheering "Go powerwalker" "Speedwalker!" etc. There were 2 people who yelled "Racewalker!" - and I knew one of them, of course. Glen Wells, age 50-54 American record holder at 50K for a while (not sure if his record still stands; it was 5:13). One woman said "Great job! I see you every year and you're awesome!" That was nice :).
The weather was decent - 70F (21C) and overcast, and slightly humid for Utah (instead of 5% humidity it was maybe 30%?). Heat wasn't really a factor for me this year, but being out of shape certainly was. The race went well until 5 miles, and then I had no legs and no oomph to keep me going up the slight incline at the end of the race, so my pace slowed a bit and I felt very tired.
Still, it wasn't my slowest Deseret News 10K ever. I finished in a respectable 58:26. Splits (mile, or 1.609km) - 8:50, 8:54, 9:33, 9:28, 9:33, 12:09 (last 1.2 miles, with the only uphill on the course). Average HR was indeed a moderate 153, though I did get up to 169 at the very end.
