Question: Mary - I am training for my 3rd Chicago marathon. My half marathon time PR is an 8:30/mile pace. Yet, when I run a full marathon, my PR time is a 10:47/mile pace. What should I be doing to narrow this difference? More speed training? More long runs? Kenyan gene therapy infusions? I start out my marathons attempting a 9:30/ mile pace, but I just peter out the last half. Bob
Answer:
Hi Bob,
Definitely go for the Kenyan gene therapy infusions! Just kidding....
Slowing down during the latter stages of a marathon is a very common phenomenon. There really isn't an easy solution because 26.2 miles is a long way to go at a steady pace! That being said, I suggest that you start out at a pace SLOWER than your goal marathon pace. Maybe start out the first few miles at 9:45 and then eventually pick it up to 9:30. Perhaps this will leave you with more energy during the final miles.
Personally, I find nutrition plays a key role during marathons. My first 3 marathons were in the days before the energy gels came on the market. The last 4 miles of those first marathons I slowed down a full minute per mile. My next 23 marathon were after I discovered GU. During a marathon I take a GU every 40 minutes. I also drink the electrolyte drink that is offered on the course. Usually I drink water for the first half of the marathon & the electrolyte drink for the last half. We're all different, but this is the nutritional strategy that has worked very well for me.
I don't know how many long runs you do in training. I would suggest that you do at least 3 long runs of 20 to 22 miles. This way your body will be trained for running for a long period of time and hopefully this will help you on race day. You should have the confidence and know that you can do it!
Wishing you steady-paced marathons in your future!
Cheers,
Mary
