Training For An Ultra || Would You Consider Splitting Up A Long Run?

The Hard Part of Running A Race Starts Long Before You Get To the Starting Line

Ultra Training

As anyone that has trained for a half marathon and longer knows the hard part is the time and effort you commit to training. We all know the perfectly planned workout week can be interrupted by life. Do you skip the long run? Do you add it to the following week?

How about splitting up the long run?

I’m up to 16 and 18 mile long runs and the recovery time that goes with those distances. and the past 2 weeks it has been unusually difficult to find the time for long runs. When that happens repeatedly it’s frustrating and can seriously sabotage motivation. This weekend I considered, instead of totally missing my long run because I don’t have a single chunk of time, what if I broke it up into 2 shorter runs. Ironically, I emailed my coach, Christine (Dream Big Runner) about my frustrations and guess what she suggested. Try splitting up the long run. At first, I thought it defeat the purpose of long runs and building endurance. I looked into the effectiveness of splitting up the long run and I’m so glad I did. According to Marathon Nation:

…no one single run is what prepares you for your race. It is the effect of training your body over weeks and months — and the ability to focus that fitness on the big day with your race execution — that will give you the results you seek.

This makes so much sense! One of my weaknesses is seeing the big picture and this situation is no exception to that weakness. I get so over-focused on each individual run I forget the grand scheme of things. As long as I’ve been running I’ve read how critical the long run is to training and, quite honestly, I enjoy the long run of my week. I’m going to try it. Not for ever long run but when I need to. My thinking is it may not always be ideal training but for my purpose, running a 50 miler, it will work:

  • I’m not missing my long run altogether
  • I’m not as frustrated with trying to find big chunks of time for increasing mileage and recovery
  • I’m less likely to consider skipping a rest day just to get in the miles

Splitting options (Marathon Nation):

Option A: Split Morning and Night (12 Hours)
This is the best possible option, as it allows for active recovery during your day and ensures you are still carrying some fatigue into that second run. It can be tricky to manage your food across a single day, as you’ll need to recovery from the first run but don’t want to be too bloated / heavy for the second effort.

EXAMPLE: Split a four hour run into 2.5 hours in the AM, 1.5 hours in the PM.

Option B: Split Night and Morning (12 Hours)
A close second to Option A, as this choice means you will be getting a bit more rest with a night of sleep between the two efforts. This additional rest option makes it ideal for beginner marathoners or folks who will be running over 5 hours to cover the long run distance.

EXAMPLE: Split a five hour run as 3 hours on Saturday afternoon, then do 2 hours on Sunday morning.

Option C: Split Morning and Morning (24 Hours)
Also know as the “weekend option,” this plan would allow you to split the long run to a pretty reasonable Saturday and Sunday morning schedule. Not as optimal as the other options listed above, but certainly very doable.

EXAMPLE: Split a five hour run as 3 hours on Day One an 2 hours on Day Two.

Option D: Split Thursday and Saturday (36+ Hours)
This is the least ideal option as your body will be 100% recovered before the next run. That said, some times life gives us no other option. Ideally you would be able to do this as a PM effort for the first run and an AM effort for the second, keeping the runs to about 36 hours apart.

EXAMPLE: Split a five hour run as 2.5 hours on Thursday and 2.5 hours on Saturday.

 Ultra Training

I’m going to try Option A this week and with any luck training will bring a smile to my face again.

Would this option work for your training? Do you think it’s an effective way to train regardless of your goal for the race? Have you ever incorporated this strategy in your training plan?

    It’s a great option and one that is proven to work. Sounds like you’re going to make the ultra training work for you one way or the other!

    I also think splitting the long run is a good idea for really slow runners, those who are going to be on their feet for 3:30 or longer just to get in a 20 or 22. Studies show that you start increasing your injury risk at that point while getting diminishing returns on training.

    i think youve got a great plan in place, jill!! it’s all about what works specifically for your body, and it’s all about trial and error! best of luck with this option, and make sure to keep us filled in!!

    My biggest problem with two a days is that they seem more time consuming. Sounds like they’ll work for you, though. I’m looking forward to following your ultra training!

      Thanks Tina. I see what you mean but my conflict seems to be finding single chunks of time for the 18+ runs. My preference is a single long run but I’d rather a split long run than none at all. We’ll see how it goes. Ultra training has been a lot of trial and error so far :)

    I’m not up to a 5 hour run yet, though as a mom who plans her long run for Sunday and is working up to a half marathon, it’s good to hear I CAN split that long run if I need it and still get the endurance benefits.

    I’ve noticed with my long runs that for me, it’s about pacing myself and mentally staying fresh. I wouldn’t want to split a long run every weekend since I would be concerned about both aspects.

    I never thought of splitting up your runs this way. It gives an old dog something to really think about and is why I love reading other’s blogs, you learn something new all the time :-) . Thank Jill and good luck with the training.

    I endorse splitting the long run, too. I agree that Option A is the best as you still get the benefit of training in a fatigued state. But let’s face it, whatever will get you out there running the mileage you need is the best plan. People have trained for distance races on aircraft carriers, submarines, deserts, all sub-optimal conditions, and managed. I think making the most of what we have available is what counts. Good luck!

    Haven’t done an ultra (or come close yet), but I have split my longer runs 10mi+ up to fit in to my schedule as easily as possible. The S.O advised to me that it’s not about the run altogether, but just that I get the miles on my feet that matters!

    Ideally you would do a long run,but splitting a long run is defintily better than no long run at all! Especially for ultra training, the only thing that matters is that you are running A LOT.

    Splitting sounds like an excellent option! I wish I had the “long run” experience to offer more advice, but I’m confident you know what you’re doing :-) I have directed family & friends to your site for your awesome recipe ideas!!

    I’ve never split up a long run, but I did reap the benefits of back to back Sat/Sun runs this cycle (long on Sat, recovery on Sun)- which is similar. The recovery run was so slow, but I really felt like a stronger runner for incorporating it in. Hope you can find a system that works for you… yes, that chunk of time is a challenge to fit in without taking over your life!

    I am looking to do a 50K next year if all goes as planned this year so it is nice to know about being able to split runs. I think Sat &Sun morning would work best for my schedule.

    I have never split up runs. If I have a four hour run I just find a time to get it done. I would hate to do a two hr run and then know I still have to go back out for another two hr run later. But good on you to do what you need to do to get it in!!

  20. Amanda @RunToTheFinish January 15, 2013 at 10:59 am Reply

    This summer i did a lot of splitting my long runs based on the requests of my coach because it would decrease the amount of recovery needed. I think mentally it didn’t feel right, but my body did seem ready for the race

    Now that’s interesting, I’d never thought of this, but it makes total sense! I’m not exactly at the long run stage (yet!), but when I get there this is something that I’ll definitely consider implementing into my running routine.

    It looks like it’s worked for you, so I don’t see why it shouldn’t do the same for me, keep up the awesome work! :)

    I’m really glad you posted this because I know that with having to start marathon training late due to my healing broken foot (almost there!) my schedule has shifted forward and there are going to be some weeks in the middle with travel that are going to make getting that long run in sort of difficult and I’ve been stressing about it a bit. I’m interested to see how splitting up that long run pays off for you and which sort of split you go with.

    As you can see, doubles work out great. Same day is the best bet because it gives you the most benefit when looking to split. I’ll do this with some shorter distances, too. Doesn’t have to be on just long runs. You can easily get 7 miles in the AM and 7 miles in the PM for a nice mid-week 14 mile run. Running on tired legs is the way to go.

    I guess you could call it splitting, but if it is on a different day, I think of it as a back-to-back. For example, on Saturday morning, I plan to run 15, then Sunday do the same. I don’t look at it as a single 30 mile run, but two separate runs that help build strength on fatigue. Welcome to the ultra life! It’s fun!

      I agree! When I saw the 2 day “split” option I thought isn’t that a back to back (which I’m already doing).

      I”m loving ultra life but as I mentioned time seems to be a huge obstacle right now. So much so I’ve started to question whether or not I can do the 50. I don’t usually doubt myself but getting the miles in lately has been so difficult. Sorry for the ramble. A temporary moment of feeling discouraged.

      I appreciate your insight! Thanks!

    I usually just try to get my weekly time or mileage in and I don’t worry too much about how it’s done. Like you said, its about being on your feet and just getting used to running. However, I do try to make sure that several of the miles are on trails/hills, because for an ultra, you will need to get your legs/body used to that!
