And by way of a cautionary tale... I offer the following....
I went out last night with my older son and did Week 6 D1... and we rocked it! Awesome! WOOHOO! And with my son! Fantastic!
So tonight my younger son asks me to take him out. He did a day or two earlier in the program but hasn't keptup as well so I figured I'd take him out for a nice W2 D1 ... good workout for him and a good "light" off-day supplement for me. He did an awesome run. I was so proud... chitchatting and laughing the whole way. I said all along I wanted to set a good example for my kids... and this is just gravy for me.
Then I got home and my wife asked if I'd like to go with her. We have hardly talked today and I knew she needed some hours in her office tonight so I figured it would be nice to spend some time and she was doing W1 as an "off day" supplement... well only did a mile and a half with my son, and pretty easy pace,... wife is planning Week 1 and another easy pace ... sounds good. So I sat while she went to slip on her running gear.
What I did NOT do is eat dinner.
So about 3/4 of a mile in I BONKED! Dizzy, distracted, sweating.... a sudden and complete breakdon like I have rarely felt before. On an "easy" 1.5 mile "supplement" run. Had to walk/hobble home and immdiately made a sandwich and guzzled a liter of water. Feeling MUCH better today.
