What Is The Target Pace For A Sub 1:45 Marathon?:
To successfully complete a sub 1:45 Marathon, the key focus is on getting PACE right. You want to train at the right pace, and run a consistent pace on race day.
In order to get around your half marathon in exactly 1 hour and 45 minutes, you would need to run an 8 minute per mile pace, or a 4 minutes 51 seconds per kilometer pace.
However, we recommend you run a little bit faster than this, in order to give yourself approximately 5 minutes of extra time to account for any toilet stops, unexpected hills, or other unanticipated delays!
Training Breakdown: What Will Your Weekly Schedule Consist Of?
These are your classic training runs; do them in the mornings or after work, at a comfortable, sustainable pace.
These runs help add mileage to your training week and get your body used to running far!
A tempo run is a training run done at your target half-marathon pace, which for a sub 1:45 half marathon is anything faster than 8:00min/mile, or 4:51min/km.
Check out our complete guide on everything you need to know about tempo runs.
Interval training involves running one fast interval, then one slow interval.
The fast intervals should be done at an unsustainable pace, whereas the slow intervals should be an easy jog.
This training plan includes 800m intervals; these should be repeated as per the amount stated in the plan.
The reason our 1:45 training program includes interval training is to help increase your speed and power.
Each week of our Sub-1:45 Marathon Training Plan includes a cross-training day; although these aren’t mandatory, we highly recommend them.
Cross-training improves your cardiovascular health and strengthens some of the muscles weakened through running, thereby reducing your chance of injury.
Recommended cross-training exercises include bodyweight exercises, light gym work, swimming, yoga, pilates, and cycling!
Check out our cross-training guide for runners to learn more.
You should be factoring in one long, slow run every weekend. These runs are all about increasing your endurance gradually.
Remember to take it easy during them, don’t push things, and don’t worry about walking breaks – it’s all about building up that time on your feet.

The most comprehensive plan you will find
I had run a couple of half marathons and was in reasonable shape coming into the plan and it was a good rise in intensity throughout. You need to want to do an event like this – I was getting up at 3am to get my long run in before kids weekend sport etc and this was hard. When you combine the plan with the online community through the Marathon Handbook FB page and website, you get complete support. Have used this plan with great success and now looking at upping the pace in the marathon space… GREAT JOB!
Remember that speed is not important for this training plan – more important is your ability to keep running the distances necessary.
The information is helpful.
10 / 10 - Got my through my race!
This plan hit so well!
Well, I have been marathoning for almost 15 years and wanted to test something new out. I tried this plan because it looked completely different than any training method before. It didn’t make sense how the running peaked, and I got to the start line exhausted and sick, clearly under rested. The marathon had actually gone pretty smoothly until mile 17, when my ankle rolled and my ACL ripped. Had to quit the race and was upset with this training plan. However, free IS free. 6/10. Would not recommend
These running plans are AMAZING. I used it for 2 half marathons and I was so surprised at how I gained fitness, even though I was ill for 2 weeks and sustained a knee injury!
I completed the half marathon in 1h37 min 😃🤗
Thanx again team!
