Searching for my "best" race

I'm searching for my "best" race. The word "best" as I use it means a combination of the following:

1. the race distance I most enjoy

2. the race distance I perform best;

3. the race distance that my body, mind and spirit thrives; and

4. the race distance where I minimize or eradicate injuries.

This morning I finished a fartlex. Overall, 7.22 miles in 56:46 with 2 miles tempos at 6:54 pace. Felt good but let's see how I feel later today and tomorrow.
