While we all await Hardrock 100 this weekend, let's take a look at the 1st/3rd/10th spread analysis. Using times since 2000, the chart helps visualize that the iconic mountain run has been generally speeding up at the top end, but seems to have plateaued and slowed down at 10th

Western States 100 Men's 1st, 3rd, 10th Spread Analysis. After taking a quick look at the last 5 years of 1st-10th data last week, it seemed natural to redo it with a chart version displaying the time spreads between 1st, 3rd, 10th place finishers. This view really helps
