Can I Still Run This Marathon with a Two Week Setback?

I am planning on running a marathon (1st one) on two months from now. I am an experienced runner with a half marathon pb of 1:36. My weekly long runs are up to 25km and total weekly km's is 40-50.

Problem is I am booked to have a nose operation which takes two weeks to recover from = no running.

running tips

I am planning on walking my weekly km's during this two week setback but am not allowed to get my heart rate up.

That leaves 9.5 weeks to prepare for the marathon.


Can I, do I?

If so - would my time be affected badly?

Should I just run the half marathon - and put off the full event till later in the year?



Answer by Dominique:

Hi Jeremy,
Thanks for your questions.

This nose operation surely comes at an inconvenient time. However, you should still be able to do the marathon.

You have built up your long run to 25k already. And it sounds like you have got a longer history of running behind you.

From that I conclude that those two weeks off will not make you lose much fitness. I think the two weeks is roughly my comfort threshold. Much longer than that and your training would be seriously affected.

So, I think you can complete that marathon.

However, I do have another piece of advice.

Your weekly mileage is decent, but on the low side for a fast marathon. You might already be familiar with race conversion calculators like the one in the link.

The race conversion calculator indicates that based on your 1:36 half marathon, you'd be able to run a marathon in 3:20. But, that's only when you'd do the right level of training.

I think your mileage is a bit on the low side still, so I would discourage you from aiming for 3:20 as the end of the race might become very painful.

It may be better to shoot for 3:30 - 4:00 and use the experience to build on for future marathons.

Best of luck and good luck with the medical procedure.
Kind regards,
