I recently got some advice from a fellow runner after a recent half marathon and i was hoping you could confirm this.
After completing the race in what was a PB of 1hr 33mins I felt like I was going to pass out from lack of energy. I mentioned to him that i had no energy left and really start to lag at mile 8 after what would be quite a conservative pace over the first few miles and after taking an energy gel at mile 5. Now this guy has seen me run 10ks with ease and thought that my 10k times were not translating correctly across to my half marathon pace, and then mentioned that I need to increase the pace at which i get into fat burning zone. His view was that I was running in the aerobic zone while doing the longer distances race, I was depleting all of my energy and this was causing the drop in pace later stages of the race. I would have to agree with him here, i cant remember a time where running longer distance i havn't had the lag in energy towards the end of the run. I can handle runs around an hour at around 7min/mile but after that i start to bleed time to around 7:20min/mile.
His suggestion to me was to run at 10k pace + 1.30min for long distances to train my body to burn fat and gradually over time increase the pace eventually working up towards race pace. I was wondering if this sounds correct and if so does any one have any plans or workouts i could follow to get my fat burning zone pace higher so i dont get this lag in energy i keep experiencing during long runs?
