I’m taking it incredibly slow tbf, trying to keep my HR down so the pace is embarrassing, finishing feeling fine. Tomorrow will be a rest or upper body weights dayWell done you. I'm no expert but The only thing I would caution is increasing your mileage too quickly increases your risk if injury. Think the advice is either. 10/20% (can't remember which) on your longest run each week. Great progress though. Give yourself rest tomorrow after those 10 miles.
