3:35 Marathon Pace Chart (How to run sub-3:35)

To run a 3:35 hour marathon you need to run at a pace of 8:12 per mile or 5:06 per kilometer.

Following the splits below (and shaving off a second), you’ll run a sub 3:35 marathon.

I’d recommend aiming to run 1-2 minutes ahead of the split target time from 10 miles, as you’ll likely come up against crowding on race day.

Is 3:35 a Good Marathon Time?

Well, what do the stats say?

Run Repeat conducted a study that contains 19,614,975 marathon results from more than 32,335 races across the globe, here is how a 3:35 marathon compares against age and gender for the races recorded:

Training Runs and Paces for a 3:35 Marathon

To break a 3:35 marathon you’ll need to do some serious distance in your training, I recommend at least 35 miles (56km) per week.

You’re also going to need to make sure you’ve crossed off these milestones for other race distances:

• A 5k in 22:20 mins
• A 10k in 46:40 mins
• A half marathon in 1 hour 37 mins

Weekly Mileage Targets

Long Run Structure

Why This Works: Incorporating varied paces within long runs enhances lactate tolerance, which helps on race day when you’ve got to maintain pace despite feeling fatigued. By practicing surges during a run, you can build up your physical and mental resilience (lots of elite marathon runners use these strategies during their training)

Alternating Long Runs: Alternate between structured long runs (easy/fast segments) and easier long runs. For easier long runs, maintain a steady, comfortable pace throughout, focusing on mileage rather than speed to aid recovery.

My Tips to Run a Sub 3:35 Marathon

Give Cross Training a go

I can not overstate enough how powerful the benefits of cross-training are.

Instead of running every day, I incorporated activities like cycling, swimming, and strength training into my routine, on my “off days”.

This helped me avoid the monotony of running.

I don’t if you’re like me, but sometimes when I’ve been running pretty much every day for months, and I’ve listened to every podcast under the sun, boredom can be a big hurdle to overcome to get me out the door.

Cross-training also strengthened different muscle groups, ultimately making me a stronger, more well-rounded athlete and reduced the risk of injury.

As these activities usually involve more equipment than running and a bit more organizing, I joined a weekly spin class, which provided a high-intensity cardio workout that complemented my running perfectly (and I love the pumping techno music).

Be Mentally Prepared

Running a marathon is as much a mental challenge as it is a physical one.

During my preparation for the 3:35 marathon, I started incorporating mental training techniques into my weekly routine.

Visualization exercises, where I imagined myself running strong and steady through different parts of the course, were incredibly helpful. I focused on the tricky 20-mile mark a lot, where I knew I’d have to overcome succumbing to “the wall”.

I also practiced mindfulness and meditation, which improved my focus and helped me stay calm under pressure.

Ultimately, when it came down to it on the day, I was able to push through the tough moments and maintain a positive mindset from start to finish.

Fit your Training Plan around your Life

One of the most impactful changes I made was customizing my training plan to fit my lifestyle and unique needs.

Instead of following a generic plan, I created a schedule that accommodated my work commitments, family time, and personal energy levels.

I included key workouts like tempo runs, intervals, and long runs, but I was flexible with the days and times I did them.

This personalized approach reduces stress and burnout, making training more sustainable and enjoyable.

By listening to my body and adjusting as needed, I was able to stay healthy and motivated.

However, this did mean I missed some sessions, and so it took longer to complete the full training plan.

I thought this might happen, so gave myself a few week’s buffer, so was able ti complete everything before the event (I’d suggest you do the same!).

Practice Running by Feel

Learning to run by feel rather than constantly checking my watch was a game-changer in my marathon training.

I started incorporating “effort-based” runs where I focused on maintaining a steady, comfortable effort instead of targeting specific paces.

This helped me become more in tune with my body and better manage my energy levels.

When I ran the marathon, this skill allowed me to adapt to the conditions and my own fluctuations in energy, leading to a more consistent and enjoyable race.

Trusting my instincts and running by feel ultimately helped me achieve my 3:35 marathon goal!
