Training through fatigue good or bad?

If I didn't train when I was fatigued, I'd never get any workouts in.

Training through fatigue can be good and bad. On some level, you're going to be tired, and you need to push through that.

However, I disagree with the manner in which you are doing it. I would not try to increase your intensity in every workout; you have seen the results of this, namely skipped workouts and an overriding sense of feeling beat up. You aren't training through fatigue with this. You just beating yourself up with no recovery. Eventually, your body will force you to recover, usually through either injury or burnout.

Being tired is one thing, being beat up is another. The saying "There's a fine line between hardcore and stupid" comes to mind right now. It seems to me you are starting to cross over that line. Doing hard workouts a couple times a week is alright. But not every day.

Setting PRs in training is nice; setting PRs in races is even nicer. You keep hammering like this, you are going to end up leaving it on the training course and won't have much left come race day.

Training while tired is one thing. Training when you are hurt, sick, or have over done it beforehand is another.

Going out and trying to PB every workout and pushing through them, ballz to the wall, isn't smart training anyway.

Yes, you should have some key intensity-focused workouts in each discipline...but they shouldn't be all out efforts, every day. And you should be making sure you get ample and appropriate rest.

What kind of training plan are you following?? It seems that you to not have the kind of structure in your training that follows the basic training principle of putting progressive stress on the body and then allowing time to recover so you get stronger over a period of time. Pushing yourself all the time when your are fatigued leads to injuries and setbacks. Rest is an impart of training to allow your body to recover to grow stronger.

OK. BTW this is not something I do every week (just the last 2 weeks). In fact it appears to me that the problem stems from the duration of recovery between the hard ride and the long run. For example If I do the Monday ride at 11:00 finish at 12:30 I am OK to run Tuesday AM. This past week and last week I couldn't get a break from work so I pushed the start time until 5:30 finishing at 7:00. The rest interval was cut from 15 hours to 8 1/2 hours. As several people have pointed out the other option is to back off the intensity of the ride if I know I don't have the recovery time. I guess I did not realize how sensitive my body is to the rest interval.

Good advice from Scout and good thing above for you to learn.  Knowing that should make it easier for you to plan your training and manage intensity in the future.
