INDIANAPOLIS — The IndyCar calendar could have a new look next year. Hulman & Co. CEO Mark Miles told IndyStar that while IndyCar continues to negotiate with Pocono Raceway about a possible extension, no agreement has been struck.

He confirmed that IndyCar’s contract with Pocono expires after the series visits the famed "Tricky Triangle" in August. This latest agreement was only a one-year deal after the two sides had agreed to a three-year pact from 2016-18.

"Right now, we’re each evaluating the prospects for growth and what it would look like," Miles said of Pocono negotiations. "Then, we'll come to some conclusions about (the future)."

After a more than 20-year hiatus, IndyCar returned to Long Pond, Pa., track in 2013. Initially, the speedway dealt with attendance issues but in recent years, crowds have grown. Ahead of last year's race, track CEO Nick Igdalsky told The Morning Call that ticket sales were up year-over-year.

However, there is a sense that some within the IndyCar paddock wouldn't be heartbroken if Pocono didn't return to the schedule next year given the pain associated with the track in recent years. The memories of Justin Wilson's fatal crash in 2015 and Robert Wickens' life-changing wreck last year remain fresh.

A loss of Pocono could be a temporary blow to IndyCar's oval count. Last year's departure of ISM Raceway in Phoenix left Pocono one of five remaining oval tracks, along with Indianapolis Motor Speedway, Texas Motor Speedway, World Wide Technology Raceway at Gateway and Iowa Speedway.

It appears, however, that if an extension with Pocono isn’t reached, the series is working on a replacement.

Miles confirmed reports out of Virginia that the series has talked with Richmond Raceway executives, saying that the speedway is “being evaluated in the context of the discussions of looking at all of our opportunities.”

While Miles didn’t refer to the series’ discussions with Richmond as a backup plan in case an agreement with Pocono isn’t struck, he did say that IndyCar is not interested in expanding its schedule of races within the continental United States. While the series continues to explore international opportunities, IndyCar is content with the number of events conducted within the U.S.

“Are we at capacity?" Miles said. “That’s a variable that depends on the when and the economics, but we’re not looking to add a new event in the Sstates at this point for next year.”

Given those comments, its seems likely that if Richmond or any other track were to join the IndyCar slate next year, it likely would only occur if Pocono or another venue were to fall off the schedule.
