How to adjust the marathon schedule to a half marathon schedule.
"I really enjoy your training schedules and the principles beyond them.
I`m up for a terrain half marathon later this autumn, and want to adjust your schedules to this race. I know that you have placed in a half marathon in the 100 day marathon plan. But - if you want to set a personal record on the half marathon and you not are going to run a marathon afterwards.. this is maybe not the best way to prepare yourself?? Or..
On the half marathon training pages from marathon-training-schedule.com, you recommend the following build-up before a half marathon:
Base-building 5k/10k endurance type training 5k-speed training Tapering
Is it possible to put together and use different training weeks from the 100 day marathon schedule to prepare yourself for a half marathon? How should the tapering phase be like compared to a marathon schedule?
Best Regards!"
Answer: Hi Lars, and thanks for a very relevant question. This is the easiest and best way to do this :
Start with the first two periods of training program (the 5k/10k and the Half Marathon Phase) Then, go into the two first week of the marathon phase before going back and repeating the half marathon phase again ! Do the Half Marathon Phase up until two weeks before the half marathon and then do the two last of the Tapering phase weeks (that will also work great for half marathon tapering)
This should set you up for a personal record half marathon race!
I'm often asked what shoes I personally recommend to help stay injury free while running (on the 100 day plan) so I'll add a little bit about it at the end of these Q and A's.
Good shoes are crucial if you want to stay injury free during your marathon journey. In general, the best is to find a shoe that fits your feet according to your foot type.
However, these three shoes will do an excellent job with their mild correction - and will work for most runners :
1. Asics Gel Kayano (click for zappos reviews for other runners views)
The legandary shoe from Asics. You cannot go wrong with this one.
The most sold running shoes ever - and by every model seems to get better and better. About the same weight as the Kayano but the fit is a little bit different.
The 2150 is a great alternative for the faster work you'll be doing in the 100 day plan. It is one of the few shoes that "feels" like a lightweight one but at the same time has more than enough stabilty to prevent injuries with the marathon type length of some of the interval sessions.
