Challenges are great for things like raising money, climbing to the top of a summit of some really tall mountain, hiking a 40 mile trail in under 20hrs. Challenges are not great for you tri training at the end of your season. It's like eating the turkey then trying to make a turkey sandwich. Where is the meat? You can't make a sandwich with just two peices of bread. It's just bread and mustard, there is no sand in your wich.
If you really want a challenge, I have one for you. One that will make you a better triathlete runner. One that will increase your runnning fitness and cause you to strike fear into the hearts of your fellow competitors. Starting NOW, I challenge you to really make a difference in your ability to race a triathlon.
My challenge is for you to run 200 miles per month, every month for the next four months. You must run at least 200 per month and you must get your long run up to 2hrs by the end of month 2 and 2:30 by the end of month 4. You must run at least one other run every week at least 60min in length and your average duration can not be below 25min run. You must swim and ride a total of 4X per week and the length of these is not really important. (in other words don't be a dummy and go ride 2x100mile per week or swim 2x9000 (tigerchik this is really for you ;-)) shelling yourself for your running.) The goal is to raise your running to a new fitness level.
If you want a challenge that will make you faster and fitter and carry over into your triathlon season making you a better racer this is it. If you want to challenge yourself in a half ass way that will not then this is not for you.
For those of you who will take the half assed challenges, may this thread run through your head as you read and watch the calfs of your fellow AG competitors run away from you. For those of you who will take the Full Ass Challenge, you better learn to count b/c you are going to run out of fingers counting the people you run past.
