One practice, one qualifying session, three completely different leaderboards. The split columns crowned Larson and Buescher. Qualifying crowned Spire. Sunday’s 400 miles only pays one of them.
Intercepted Audio “ ” One practice, one qualifying session, three completely different leaderboards. Sunday’s 400 miles only pays one of them. Indianapolis Motor Speedway · Brickyard 400 · Saturday, July 25, 2026 · By PitByNumbers Staff · 12 min read Context makes the splits matter more than usual this weekend.
This was the only practice of the weekend, on a right side tire that has never been raced anywhere, and the run data below is the only public evidence on earth of how that tire behaves past lap five. Most of the field treated it that way: only a handful of drivers ran 15 consecutive laps, exactly one ran 20, and the broadcast booth said the quiet part on air, that with so few long runs, the 5 and 10-lap columns are the only honest way to read the field. One methodology note.
The times below are computed from the full lap-by-lap timing data, split into runs, using one consistent method across all 39 drivers, so the ranks are directly comparable. NASCAR’s Lap Averages app clocks laps at a different timing line and its absolute figures can drift slightly from these; the rankings are the product. Toggle to TIMES for raw seconds.
One real kiss and two warning shots. Bubba Wallace found the softball at the end of the short chute early in practice, a hard enough hit for right-side damage, a garage repair, and a late return that salvaged only 15 green laps for the defending winner. The warning shots were quieter and arguably scarier.
Ryan Preece’s left rear tire went flat five or six laps into a run on the never-raced right side package, on a Ford, the manufacturer the booth immediately noted has owned most of the recent rear tire trouble. And Tyler Reddick radioed that his grip vanished mid-session and wondered aloud whether Turn 2 was coming apart, the same Turn 2 that needed patching during the Indy 500 in May. In qualifying, Michael McDowell nearly wiggled into the wall off Turn 3 and still qualified sixth.
On a 400-mile Sunday, every one of those threads gets pulled. Three boards, one grading rubric. First: the win market’s job Sunday is reconciling Larson’s splits with Hocevar’s clean air, and the honest answer is that a caution-timing coin flip decides which file cashes.
Second: the fade list wrote itself in public. Nemechek at P2 on the chart with the 29th-best run pace is the single largest gap between price perception and race pace on the board, and Bell’s P1 practice headline is attached to a car that qualified 23rd with a complaining left rear. Third: our Friday morning Zane Smith flag at plus 700 got no help from this data, and the writeup above says so plainly, because a betting site that only recaps its winners is a marketing site.
The full Cup card locks Sunday morning. Measure every number the books repost tonight against the splits above, because the books watched the same qualifying everyone else did and only one leaderboard from this weekend actually races. The chart crowned Toyota and the chart is qualifying-trim theater.
The splits crowned Larson and Buescher, the two most honest race cars of the weekend. Qualifying crowned Spire, handed Hocevar the cleanest air at the hardest passing track on the schedule, and buried half the practice heroes in the pack. Sunday is 160 laps of those three stories fighting, on a tire whose twentieth lap exactly one team has ever seen.
Bet the version of the truth with the most evidence. The board above is where the evidence lives.
