Martin suggests eating real food. As for the plan, I would suggest focus. Concentrate on the last 10 lbs; training for an ultramarathon on top of fat loss would be brutal. Cutting out the running would be the best plan.
One setup that might work for you with the running:
4 off days/week: 17 hr fast; 7 hr feeding window, low carb, high protein, hypocaloric (maintenance - 10-20%)
3 training days/week: shorter run, break fast with a small protein + carb meal; fast until 2pm, break fast with a two small high protein meal, workout, large carb + protein meal; aim for isocaloric or slightly hypercaloric (maintenance + 0-10%)
Only you can tell if that drives you into the ground.
