Strong Front Half Fuels Steady Marathon Finish Theodore Li completed the Boulderthon Marathon in 4:13:20, averaging 9:40 per mile. Li's race showed a clear two-part shape: the opening 13 miles clicked by between 8:00 and 8:34 per mile, holding an 8:20 elapsed pace at the halfway point. From there, the pace gradually eased, with a rougher stretch near mile 15 (12:06) before settling into the 9:0011:00 range through the high teens. The closing miles, including the stretch past the lululemon Power-Up Zone around mile 22.5, slowed further into the 11:0013:00 range as he worked toward the Pearl Street Mall finish. That first-half effort, sustained at altitude above 5,000 feet, stands as the strongest running of his day, and maintaining a touch more of that rhythm into the closing miles is a worthwhile target for next time.
