why don't you train for a half marathon or something?

I run about 3 and my knees can't take anymore

Not yet, but Im certainly trying ;)

:clap:

I'm going to do a mud run with Amy's cousin. I don't think I could run 13 miles. Today was the furthest I've ever done and I'm feeling it in my calf muscles.

You absolutely could. You could run a marathon if you wanted. Just a matter of further conditioning. I have a DVD as part of a triathlon training series that has lots of tips on how to condition. Getting better at endurance stuff is NOT just running longer and longer distances daily at all. Too much to cover here. Nutrition and calorie timing also start to be critical.

I wasn't actually out of breath so as far as cardio is concerned I think I could do it. The problem was fatigue. The last two miles are a slight up hill coming over the freeway which is when I really slowed down. I'm not interested in doing a half marathon though. I do want to do the mud run though.

The fatigue is the combination of glycogen depletion and your body failing to take up lactic acid.

I'd like to do the full Iron Man some day, which ends with a full marathon, but it take 30+ hours a week for about a year to prepare properly and my wife is not too keen on me taking long ocean swims, so probably just a fantasy.

Might get into spring tris and bis though. More well suited to my body type anyway. I'm way too stocky/heavy and a little short legged to be even remotely competitive at the long stuff. Those guys are freaks.

Man for the past week I have had zero motivation for anything. I've been sleeping for about 12 hours a day and not eating, I'm really tired of feeling like this but I feel like I can't get out of this funk. I think not having transportation is not helping the situation. Especially since it's been cold and raining and I can't run or bike ride anywhere. I can't wait for Steve to come back from his vacation.

Your welcome to borrow my Jeep in the meantime if you want. I can drive out and you drive me back. It's dirty, a litle leaky around the sides and the clutch chatters a little sometimes, but it runs fine and the heater works.
