Let me know how that works out in 6 months. You won't be running 10k 5 times a week or anywhere near that.
why not pick a fitness goal you'll actually reach? working out 2 to 5 hours a week would be a nice goal.
It's certainly not at all impossible. 10k per day really is not that bad and I personally know of people in REAL life that do 70+ *miles* per week. I'm not trying to hit it in the next week, I'm doing this long term of course. Even if it takes me 2 years I'll get there.
