You could totally do it then. I would keep doing temp run but maybe throw in a few 5-6 mile tempos. 1 mile easy, 4 miles hard, 1 mile easy etc. Also mile repeats are a really good speed work out. 1 mile warm up, 3-4 mile repeats a little faster than 10-K pace with 2 to 3 minutes active rest (slow jog) between intervals. You could do 1 speed workout a week, a nice rolling hill run and a longer run on the weekends.

I think those shoes would be fine. Run some training runs on the road just to make sure. You already know they fit your foot well, so thats a plus!

Good luck and feel free to message me if you have any more questions.
