Date: Sept. 27, 2026 Participant: Sidharth Senthil #31181 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Third Straight Year, Third Personal Best Sidharth Senthil crossed in 40:02, finishing 21st overall and 15th among men in a field of 3,071, while topping the 15-19 age group. That mark keeps a clear trend line: 52:26 in 2024, 43:42 in 2025, and now his fastest showing yet. The race opened fast, with a 5:53 opening mile, his quickest of the day, before settling into a rhythm between 6:14 and 6:41 through the middle miles. Cumulative pace held near 6:20 per mile deep into the race, a sign of steady effort rather than an early spike fading out. The closing mile slowed to 7:37, worth a look as an area to shore up given how strong the pace was beforehand. All of this came at over 5,000 feet of altitude in Boulder, adding context to the effort behind these times.
