Race Day Tips
Arrive early to the expo and start line to avoid the crowded first mile, as it can be a zoo with many runners, especially if you are in a seeded corral. This will help you settle into your pace more comfortably.
Be prepared for a few small hills between miles 15-18, which can be a surprise on an otherwise flat course. Use these sections to your advantage by maintaining effort and gearing up for the final flat stretch.
Consider starting conservatively in the first few miles to avoid the congestion and allow yourself to find a rhythm before pushing the pace. Many runners reported feeling good after settling into their pace around mile 4.
Aid stations typically offer Gatorade Endurance and water, so practice with these products during training to avoid any stomach issues on race day. Some runners also recommend carrying your own gels for consistency.

Reviews & Race Reports
Flat and fast course with strong crowd support. Watch out for fatigue after mile 20.
Crowd Support — The crowd energy is a highlight, especially from mile 25 onward. Runners felt uplifted by cheers, signs, and even bells, making the final stretch more bearable.
Navigating the Start — The first few miles can be crowded and chaotic. Many runners struggled with GPS accuracy and weaving through slower participants, so plan to start conservatively.
Hydration Strategy — Aid stations are plentiful, but some reports mention understaffed stops, particularly around mile 12. Be prepared to grab water on the run and consider your fueling strategy to avoid stomach issues later on.
Final Miles Challenge — Expect to battle fatigue and potential cramps after mile 20. Many runners reported hitting the wall around this point, so pacing early is crucial to maintain strength for the finish.
Struggled in the last 5 miles but held on for a solid finish.
The weather was perfect, about 45 degrees at the start without any wind. My plan was to take 6 gels (45g carbs each), throughout the race, at 15 minutes and then every 30 from thereon. I settled in behind the 2:55 pacer group and cruised with them to the half way point. I was surprised how many runners were in the group, it felt fairly packed all through the first half.
Skipped hydration stations, finished strong with a negative split
Race plan went nearly perfect. Weather was spot on at 45 degrees with minimal wind. My HR was a little higher than I would've liked the whole way, but my body felt good so I chose to be aware but not obsess over HR. Effort level was the perfect mix of comfortable, but still ambitious for the first 20 miles.
Felt strong in the second half, qualified for Chicago & Boston!
Race day weather - perfect. Couldn’t have asked for better. Especially considering it snowed the next day! Had been debating pace all week, but really wanted to give myself a shot at 3:20 (main goal was to qualify to run Chicago next year) - so I decided to go for between 7:30-7:40/mi pace during the first half, trying to keep it closer to the 7:40 range in the beginning so I wouldn’t burn out.
Felt relaxed and controlled, despite usual late-race fatigue.
Truly cannot recommend Indy enough. The weekend was seamless from start to finish. Easy, inexpensive flight from NYC, plenty of affordable hotels walkable to the start and expo. I ate ~450–500g of carbs the two days before the race. Race morning: 2 Maurten solids, a few graham crackers, coffee, beet juice. I jogged about half a mile to warm up and hopped into the A corral 15 minutes before the start — incredibly easy logistics.
Felt heavy at mile 12 but maintained pace to a 12-minute PR
At mile 12 I hit a water stop that was fairly understaffed. I ultimately had to STOP and pick up water at a table. You know how your legs feel when you end a long run and they start to seize up? This happened to me at the water stop.... at mile 12. My legs just felt heavy and tired.
