We are about to publish our international men's preview but I'll share the following excerpt for you.
Most marathoners at Kirui's age (35) would be hesitant to change things up, but Kirui did just that by training for Chicago in Patrick Sang's group with Eliud Kipchoge. Kirui told RunBlogRun's Sabrina Yohannes that he still works with coach Renato Canova as well but that he's been in Sang's base of Kaptagat for this buildup.
"I went like three months ago to Kaptagat," Kirui told Yohannes. "I wanted actually to see these guys; they are running the best times, so I wanted also to catch up to the times. Because I'm like a 2:05 guy; if I join their group, I will improve a lot."
