These are just a few of the questions that go through my head while I train for the TIR. I'm about halfway through training and while all the old familiar aches and pains are back for the reunion, it's starting to make me weary of jogging. I'm not trying the Jeff Galloway method this time around, which probably would be the better bet, given my self-diagnosed tendinitis. Last time I tried it though, I misunderstood the training plan and developed a hybrid method that was halfway successful...Half-assed effort leads to half-assed results when it comes to running.
BUT, remove the knee pain and random physical annoyances (i.e. foot tingles), and I do enjoy jogging. If I get into a rhythm and focus (or even clear my head), it becomes liberating. I remind myself that not everyone can do what I do due (da do do do) to physical or mental constraints, and even where I'm at in the training plan now, I'm no where near where I was when I started. Training is a proven method to achieving a herculean feat with patience and method. But with that said, in my TIR training plan, I am also accounting for the days where I modify the distances set out for me. Usually it's because of my knees, sometimes its because of my busy schedule, and occasionally it's because I've reached my limit. My body is telling me that I should go no further. This is something that is beyond the knee pain. I thought it was just a lack of focus, but then I started paying closer attention. I acknowledge the probable fact that I could continue on and run those extra 10 minutes, but this is a rare time where I agree with my subconscious about how even though its a good idea to stick to the plan, I need to know when to not push.

Where do you strike a balance between pushing yourself and knowing when to stop? Aches and pains come and go. There are so many pulleys and levers in the human body; it's a complicated science, I'm realizing, to be the ultimate runner. Some people have it naturally, but as it has been true with almost everything else in my life, jogging/running does not come easy. If you push too much, you break something. The lever snaps and your IT Band is shot. You don't push enough and you never get prepared for that 300 ft incline.
Anyway, I've experienced over and under preparedness with the TIR with the last two years of running it. I just wish it didn't always feel like a gamble. I wonder if this year is a push too much or push too little.
