I was curious to compare this year's miserable heat during the Psummer Psycho 50k to last year's miserable heat. For the first three hours, they were similar, but as the day went on this year became a lot warmer. Then I was curious to see how the increase in temps impacted my pace. It's pretty clear to see how those temps had a significant impact on my third loop.
