To run a 2:35 hour marathon you need to run at a pace of 5:55 per mile or 3:40 per kilometer.
Following the splits below (and shaving off a second), you’ll run a sub 2:35 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.

Training for a 2:35 Marathon
Is 2:35 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 2:35 marathon compares against age and gender for the races recorded:
| Overall | You’re faster than 99.7% of all runners. |
| Male | You’re faster than 99.5% of males. |
| Female | You’re faster than 99.9% of females. |
| <20 | You’re faster than 99.0% of under 20s. |
| 20-29 | You’re faster than 99.2% of 20-29 year olds. |
| 30-39 | You’re faster than 99.6% of 30-39 year olds. |
| 40-49 | You’re faster than 99.9% of 40-49 year olds. |
| 50-59 | You’re faster than 100% of 50-59 year olds. |
| >60 | You’re faster than 100% of over 60s. |
Training Runs and Paces for a 2:35 Marathon
To break a 2:35 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 16:15 mins
- A 10k in 31:20 mins
- A half marathon in 1 hour 11 mins
Pace for Training
| Pace | Mins per Mile | Mins per KM |
|---|---|---|
| Easy | 6:26 | 4:00 |
| Steady | 5:43 | 3:33 |
| 10k | 5:14 | 3:15 |
| 5k | 5:02 | 3:02 |
| 1 Mile | 4:40 | 2:55 |
Weekly Mileage Targets
| Target Mileage: | Gradually increase your weekly mileage from 40 miles (64 km) to a peak of 68 miles (109 km). |
| Incremental Increase: | Increase mileage by approximately 10% each week, with every fourth week as a recovery week where mileage is reduced by 20-30%. Make sure to taper for the last 1-2 weeks. |
Long Run Structure
| Total Distance: | Build up to long runs of 20-22 miles (32-35 km). |
| Segment Example: | First 5 miles (8 km): Easy pace, heart rate 140-150 bpm (approximately 6:45/mile or 4:12/km). Next 1 mile (1.6 km): Fast pace at 5:00/mile (3:06/km). Next 5 miles (8 km): Medium effort, heart rate around 160 bpm (approximately 6:00/mile or 3:44/km). Repeat: Repeat the segment twice (5 miles easy, 1 mile fast, 5 miles medium), you can taper the final 2 miles if required. |
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.
Speedwork Sessions
| Short Intervals: | – 800m repeats at 2:37 per interval (3:15/km). – Aim for 6-12 repetitions with equal time for recovery. |
| Mile Repeats: | – 1 mile repeats at 5:15 per mile (3:15/km). – Aim for 6-12 repetitions with a 1-2 minute recovery jog. |
| Longer Intervals: | – 2 mile repeats at 5:25 per mile (3:22/km). – Aim for 5-8 repetitions with a 2-3 minute recovery jog. |
Recovery and Rest Days
| Rest Days: | You don’t need to incorporate rest days if you are using recovery runs, but I recommend taking 1 (or a max of 2) per week to allow your body to recover and prevent overtraining. |
| Easy Run Days: | Include 1-2 easy run days per week at a relaxed pace of 8:30/mile (5:17/km), covering 5-10 miles (8-16 km) per day. Try to keep your heart rate below 140 bpm on easy days to ensure proper recovery and aerobic development. |
