Kyle Larson's Shocking Admission Before NASCAR Title Race

Bob Pockrass (@bobpockrass) on X reported Wednesday evening that Kyle Larson is running the California International Marathon on Dec. 6.

That is the Sunday after the NASCAR Cup Series championship race at Homestead-Miami Speedway.

Larson, the defending Cup champion, is in the middle of a title fight with Christopher Bell and Denny Hamlin.

He leads Bell by 67 points and Hamlin by 70 points heading into the finale.

But his training schedule is drawing attention for a different reason.

According to Pockrass, Larson plans to run 15 miles on Thursday morning.

Cup practice at Homestead is scheduled for early Friday evening.

That means Larson will run the equivalent of more than half a marathon less than 36 hours before he gets in his No. 5 Hendrick Motorsports Chevrolet.

Pockrass asked Larson how the marathon training has helped him in his title quest.

Larson’s answer is not included in the X post, but the fact that he is training at all — at this level, at this moment — is unusual.

Most drivers taper their physical activity in the final weeks of the Chase.

Some focus on simulator work, film study and rest.

Larson is doing that, plus logging high mileage on his legs.

The California International Marathon is a certified course in Sacramento.

It draws elite amateur runners and a handful of pros every December.

Larson is not a professional runner, but he is taking the race seriously enough to run 15 miles the day before Cup practice.

That level of commitment raises a natural question: Does the marathon training help or hurt his performance on track?

Drivers in stock car racing need core strength, neck endurance and cardiovascular fitness.

A Cup race at Homestead lasts about 400 miles, roughly 3.5 hours.

Temperatures inside the car can exceed 120 degrees.

Heart rates stay elevated through green-flag runs.

Physical conditioning matters, especially in the closing stages of a long run.

Larson has never hidden his interest in endurance sports.

He has run half marathons before and has talked about wanting to do a full marathon for years.

This year, he made it happen — and he is doing it during the most pressure-packed week of the season.

From a pure points perspective, Larson does not need to take risks at Homestead.

He can clinch the championship by finishing 28th or higher, regardless of stage points.

He can also clinch by scoring eight stage points, which means finishing third in Stage 1 or Stage 2, or seventh in both.

The fastest-lap bonus reduces either requirement by one point.

Because Larson holds the tiebreaker over both Bell and Hamlin, nine total points guarantees him the title.

That is a comfortable position.

But comfort does not explain the marathon training.

Larson appears to be using the physical challenge as a mental tool.

Running 15 miles requires discipline, pacing and tolerance for discomfort.

Those are the same qualities needed to close out a championship race under green-flag conditions.

Bell and Hamlin face much narrower paths.

Bell must win the race and score at least 14 stage points, or 13 stage points plus the fastest lap.

If he does not finish eighth or higher in Stage 1, he is eliminated.

Hamlin must win and score at least 17 stage points, or 16 stage points plus the fastest lap.

He needs to finish fifth or higher in Stage 1 just to stay alive.

Neither scenario matters if Larson finishes 28th or higher or scores eight stage points.

That is the math.

But the story Pockrass reported adds a human layer to the numbers.

Larson is not just managing a points lead.

He is training for a marathon, running 15 miles the morning before practice, and racing for a title the same week.

That is not typical.

It is not reckless, either.

Larson’s team, Hendrick Motorsports, has not commented publicly on the training schedule.

But the team has supported Larson’s outside interests before, including sprint car racing and midget racing.

A marathon is a different kind of extracurricular activity.

It does not involve crash risk or equipment failure.

It does involve fatigue, muscle recovery and timing.

Running 15 miles on Thursday means Larson’s legs will be under load less than 48 hours before the green flag drops on Sunday.

If he paces himself correctly, the run could serve as a light training stimulus rather than a drain.

If he pushes too hard, he could carry residual soreness into the car.

Larson has been open about how running helps him clear his head.

He has said in past interviews that long runs give him time to think through race strategy without distractions.

That mental clarity may be the real value.

At Homestead, the track is a 1.5-mile oval with progressive banking.

It rewards drivers who can manage tire wear over a run.

Larson won at Homestead in 2022 and has finished in the top five in four of his last five starts there.

He knows the track.

He knows the car.

He knows the points situation.

The only unknown is how his body will respond to a marathon training block during championship week.

Pockrass’s report does not include any concern from Larson or his team.

It simply states the facts: Larson is running the California International Marathon on Dec. 6, and he plans to run 15 miles on Thursday morning before Cup practice.

That is the kind of detail that makes a championship weekend more interesting.

It is also the kind of detail that only comes from a reporter who watches the sport closely.
