Sergio Ráez Villanueva, or simply Sergio as he's known by many, really came into the consciousness of the running nation when as a student at McMaster he won the 2018 10,000m Canadian Championship in an all out sprint finish, qualifying him for the NACAC games. But shortly after the Peruvian-born Canadian ran at those NACAC games, he all but disappeared, with only a few out of character races sprinkled in. Flash forward to last month though, and out of nowhere, word came that Sergio had run an unofficial 63:57 debut half marathon time trial, with next to no taper or specific training. Of course, we had to follow up, and that's what we do on this week's episode
