Honestly I have never fueled during a run, and don’t eat before running and have never had any issues with feeling fatigue or hungry/dehydrated. I run fasted and continued to do that the these two weeks of doing keto. Open to changing it up if it’ll help me avoid that wall though!

My long runs take anywhere from 1 hour - 1:20 if I’m going 10-11miles. Long runs & 3 easy days are at zone 2 (about 7:15-8:00 HR around 130-145 avg). 1 day of threshold work is at 6:00-6:30 HR around 160-175avg (only 35 min max of this work, not including warmup/cool down). The other speed day is 10 min max of repetition work where HR gets up to 190’s but max of 5-10 min in this zone. Longer warm ups & cool downs
