Those are pretty strong 800's! I've been doing those once each week and add 1 more after every two weeks. Watch the speed commence! Good luck.
Sometimes after a major accomplishment, it can become "mundane" to write about other things. I know I've struggled, this year, without an Ironman in my face. I had a huge PR marathon, the return to the site of my first fiasco of a triathlon, and a half-IM in two days. And I have the prospect of a 50-miler on the plate. Even so, it's just been different than last year with IMKY.
Don't worry, you'll find things to write about. And everyone will keep checking in to see what's happening. Just remember to put up the occassional, "Hey, I'm here, but nothing is going on" post. That lets people know you haven't abandoned the site.
I wouldn't say that post contained 'nothing'. It's good stuff. We all have lulls now and again. Hell, it's summer...it's all good.
