Can a 14:30 5ker run a 2:24 marathon

A 14:30 5000m runner can run 2:18. Potentially. But this may have little to do with you.

What's the equivalent? Probably 2:22 or 2:23. But that's the ideal and there's a chance they may bonk and not crack 230.

This^. I had a friend that was 14:28 / 2:17

I think the marathon is going to surprise you in a rough way. I ran 3:45 for 1500m, 14:17 for 5000m, 29:05 for 10,000m. I figured I'd be able to run 2:15 I ran 2:23. Craig Mottram ran 3:31 for 1500m, 12:58 for 5000m, and I think 27:38 for 10,000m and could only manage a 2:28 marathon. Some people are suited for the marathon and some just are not.

Something like that. Maybe a bit faster with the super shoes. But yeah there is some chance they hit mile 20 and die.. for a guy who has never run a marathon 2:24 is probably a decent betting line given all the variables (what if it is a bad weather day, injured during build up,...)

Can? Yes. Will? Who knows.

I've seen a 13:48 guy run 2:35. Marathon isn't for everyone.

14:40s gives someone a shot at sub-2:19. Some can do it a little slower. Can you run a 2:24 -- sure but can you do it now who knows. 17 @ 6-flat feeling however it felt is still 9 miles short & 30s/mile slow. You can definitely run 2:24. No idea if it comes easy or not for you.

I think that would be a faster 5k than many women that have run around 2:24 for a marathon....

1430 definitely indicates the talent to likely be able to run 2:24 or significantly faster.

But how long do you have to train for this? If you have to do this without any marathon specific training, it could be really tough. There is a good chance the wheels fall off and you fail, you won't really see the cracks forming until the 21 or 22 mile mark.

If you have 6 months to train, then you've got a very solid chance of winning the bet fairly easily.

Yes this is totaly possible - I ran those times myself last year. As other posters have said though, marathon training is a very different game to 5k training. You'll probably need several months of training including some fast/hard long runs to adjust to the pounding to hold 5.30s for 26.2. Once you get going on the training you'll get a better feel of how your body is adapting and if 2.24 is on the cards.

Also, will this be a first marathon? What's your half marathon PR? This will give a good indicator of what's possible for you.

My 5000 pr was 15:11 at the time I set my marathon pr of 2:18:27. I suggest that you focus on long runs, long intervals (2km/3km), good mileage (90-100mpw) and some long uphill runs if you have access to them. Good luck to you

Some of the amateur bowerman guys have pretty slow 5k times relative to their marathon pb (at CIM).

Patrick Reaves has ran 2:17 and Peter Bromka has ran 2:19, neither of them has run sub 15.

Some can,some cant.Theres probably some 14.30 guys who can run a 2.14 marathon,assuming its their best event,and theyre a true long distance runner.

Your Mottram reference is a little misleading. He stopped competing seriously in 2013 and his marathon was run in 2016. At the point in his running career, it’s unlikely he pushed himself.

Objectively, 14:30 is a much superior performance than 2:24, but it doesn't mean you can do it. 30 women have run under 14:30 and 232 have run under 2:24.

Depends. Did you (or these guys) run their 5km PRs on the track in non-super spikes....but then run the road marathon in Supershoes?

The shoes alone in a road marathon (if compared to an old track 5km PR in non-super shoes) are going to give one an edge probably by 2-3 minutes in a marathon at least.

Back in my day I ran my 5km PR (14:29) on an indoor track in old crappy spikes about 8 months after I ran a 2:21 in college (in old regular EVA foam shoes with no carbon plates). Eventually got down to 2:16 high at Hansons and the 5km PR stayed the same. I doubt I could've gone much under 14:20 (if ever), but the focus has to shift to more long Tempo efforts (5 x 2-miles, 3 x 3 miles etc) and 20-22-mile long runs. 100mpw + also helped with the marathon.

Lots of guys could run sub 14:30 for 5km in college at the DI level. Not as many will be able to translate that to a sub 2:18 necessarily...but a 2:24 is very possible and quite a bit "easier".

Your friends are idiots if they think 2:24 is more impressive than 14:30, regardless of whether they win the bet.

Exactly. Ask Sara Hall or Keira D'Amato or Jordan Hasay if they can run 14:30 for 5000m.
