A substantial number of the horses eligible for the 2018 Pepsi North America Cup will be in action this weekend 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 2018 Pepsi North America Cup.

This year's edition of the $1 million Pepsi North America Cup will take place on Saturday, June 16 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.

Of the horses listed in the top 10 of the Spring Book, nine have either qualified or will qualify this weekend and seven -- Stay Hungry, Lost In Time, Pedro Hanover, Shnitzledosomethin, Hayden Hanover, Nutcracker Sweet and Summer Travel -- were in action on May 4 or will be in action on May 5.

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 4, 2018.
