Are You Listening?

What do you do when you hear bad news? Do you dwell on it and let it affect your future? Does it make you want to fight even harder for what you want? What should you do? I think you have to find a healthy balance. You can't let your life and attitude be affected by things you can't control, and yet you must develop the skills of a good listener. History is filled with examples of leaders that pressed on in the face of adversity to accomplish many amazing things. Likewise, there are many examples of people who ignored the voice of reason and forged ahead... straight to their own destruction. This is the same in life and triathlon. God has a purpose for you and allows you to suffer trials so that you can be refined like gold being refined by the fire. His spirit, at the same time, is speaking to you. If you are not inclined to believe that, you might miss a blessing, or worse, plod headstrong into even more suffering. If you stop running the first time you get a stitch in your side, you're going to miss the fitness benefits that are gained when you push through the pain. And if you keep pushing through that strange little twinge in your knee run after run without giving it a rest, you might risk the possibility of not being able to run in the future. You must be able to listen.
I'm struggling right now with exactly that. I've set a goal of ironman texas on may21st. After being hit by that car during a training ride back in June, the doctor has told me to temporarily stop riding my bike and limit my running to a slow-paced 20 mins at a time. We don't exactly know why my hands go numb when I'm riding my bike, and apparently the doctor sees some lingering concussion symptoms even 5 months later. At what point do I decide that the ironman is no longer a realistic goal? I still have 6 1/2 months of training left , and I have already built my base level of fitness to a greater level than ever before. But... If I don't spend a TON of quality time on the bike over the winter, I will be in serious trouble come May. I guess I'll just wait and see... or... I guess I should say... hear.
