A substantial number of the horses eligible for the 2017 Pepsi North America Cup were or will be in action this week at racetracks across the continent.

As stakes season picks up and three-year-old pacers start to target Canadian harness racing's biggest prize, Trot Insider will track the contenders and eligibles as they prepare for the 2017 Pepsi North America Cup.

This year's edition of the $1 million Pepsi North America Cup will take place on Saturday, June 17 at Mohawk Racetrack. The eliminations will be held a week prior.

For the past several years, Trot Magazine's Pepsi North America Cup Spring Book has served as an initial barometer for the colts and geldings that may be in the running for the sophomore pacing set's single biggest payday. As in past years, the Spring Book appeared in the April issue of Trot.

Here are the horses that have made the April 15 N.A. Cup nomination payment and have raced or are in-to-go as of May 22, 2017. Horses making debuts on this list appear in bold.
