Your Marathon Program is KILLING You

Following a pre-written program for marathon training.. or 10k or any other distance.. comes at a price. The person who wrote the program may have never met you.. and if they have met you, they likely do not know how much sleep you got last night.. how stressed you are with the project deadline looming at work.. and all the other variables which determine whether you should really hit the scheduled 16k long run on Saturday.
