Time gap between half Marathon and Marathon.

I am 43 and running half marathon on Feb 9. I have been running for past two months and cover almost 20-25 miles each week . Running half marathon should not be problem for me as I have ran one last year too. It usually takes me around 2 hours and 15 minutes to complete half marathon.


I have also registered for marathon on Mar 16 but little skeptical about it because I am not following any training schedule for running a marathon. However, I am ready to run around 30 miles per week starting from this week.

Can somebody please advise me if that would be enough for a novice runner like me to successfully run marathon on Mar 16?

    Time gap between half Marathon and Marathon.

    As the runner you met in Houston said, you don't want to overdo it or jump into it too fast.  If you have only been "running" for two months, the half may be too much.  If you've been running longer (your blog implies more like a year) and only training for the half for two months . . . well, you're better off but would be well advised to go easy at the half.


    For the marathon, you could conceivably do it, but most plans recommend peaking around 40 miles per week, with a 20 mile long run.  And plans usually run 16 weeks or more.  Take a look at the Hal Higdon Novice 1 plan to get some idea.


    Good luck.

    You have not been running enough to run a marathon in Mar.  Can you do it,

    probably but it will not be pretty!!!  I would advise running another year as you have been and run that marathon next year, but if you must run it plan to take walk beaks often!

    Re: Time gap between half Marathon and Marathon.

    I figured I would let someone else say it more emphatically than I did.  You would be woefully undertrained for a marathon in March.  You could do it, if you're careful and persistent and use a lot of walking breaks.  A marathon is not like a half-marathon, only longer.  You can fake a half. You can't fake a full.  That is, you can do a half under-trained and still feel OK afterward.  Run a marathon undertrained and you will feel like crap before you're even close to the finish.  Consider that the halfway point of a marathon is considered by most to be 20 miles.  Have you run 20 miles lately?


    To get back to your original question, sure, running 30+ miles per week will make it better (not necessarily easier).  But you will still be undertrained.  I'm not trying to discourage you from running a marathon, just encouraging you to do a better job of training before you do.  Good luck in any event.

    Len took the approach of whether or not you could finish a full marathon with your training schedule; and he was spot on with his analysis.


    I am going to take a slightly different approach; you may well be able to gut it out for the full marathon, but you may well also injure yourself to such an extent you'll never run again (or at least not for a very long time).  Long story short, your training is woefully insufficient for preparing your body to endure the rigors of a marathon, errr, unless you walk most of it.

    • 1-mile (point to point, gravity assist): 5:50
    • 2-mile: 13:49
    • 5K (gravity assist last mile): 21:31
    • 5-Mile: 37:24
    • 10K (first 10K of my Half Marathon): 48:16
    • 10-Mile (first 10 miles of my Half Marathon): 1:17:40
    • Half Marathon: 1:42:13
