Sometimes we need to change it up a bit. My own experience follows. Feel free to comment about yours too 🙂
This year for fitness events I signed up to an out of town trail run. I also went The week before to familiarize myself with the course too.
The 10k Trail run with Rocky ground, lil mud, and roots was an awesome experience. Heard water nearby at times too. Excellent stuff with cheers from staff and back and forth with other runners. It was at High Cliff state park in eastern WI
