The 3rd Annual Indy Piston Endurance Run is Central Indiana's premiere ultramarathon located entirely in Downtown Indianapolis running along the paved trails in White River State Park.  The entire course is lit, flat, fast, and absolutely gorgeous!  Indy Piston is perfect for the first timer or seasoned runner chasing a new PR.  Accommodations for athletes traveling into town couldn't be any better with numerous hotels, restaurants, entertainment options, and sights to visit within blocks of the start/finish.  The event is held annually in early June offering prime weather conditions for all 30hrs ensuring athletes can focus on their 50k, 50mi, 100k, 100mi distance at hand.  Everyone knows Indy is the racing capital of the world, and now it's true for Ultra athletes as well!  Petey the Piston, and the whole crew behind Indy Piston Endurance Run look forward to hosting you June 3rd-4th, 2023. 

New Host Venue!

Race Headquarters will be at the National Institute for Fitness and Sport (NIFS).  NIFS is only three buildings west of the previous host venue.  Why did the location change?  Several positive benefits!!  Here's a few:
1. Indoor restrooms and locker rooms with showers! during NIFS business hours.  They are open from 7:00am-5:00pm both Saturday and Sunday.  
2. A paved patio for our main aid station to enable us to better accommodate all Indy Piston participants.
3. We determined the most congested area of the old course utilized by other WRSP patrons was right by the Indiana State Museum.  Moving to NIFS removes that section of the course to help increase safety and provide a better overall experience for Indy Piston participants.
4. Packet pickup will be at NIFS on Friday evening from 4:00pm-7:00pm.  This will allow participants to preview the venue and course layout in the daylight before the race.    

Indy Piston Endurance Run is the perfect ultra for veterans and beginners alike!  With a fully lit course and aid stations roughly every 1.5 miles, we have what you need to keep your pistons fueled and firing all cylinders throughout the race!

New Sunday Half Marathon!

Looking to run a half marathon each month of the year?  We got ya covered for June!  A Sunday morning Half Marathon has been added for 2023!  Help keep the camaraderie alive for the ultra participants in the final hours of their race while you race for a new PR of your own!  The course is flat, fast, and aid stations every 1.5 miles!
