AM - Very easy run this morning. The heat and humidity makes running fast nearly impossible, but had a better pace the last mile. Took a few breaks to drink enough fluids.
PM - Heat index is sky high today so did 6 on the TM all easy. Strapped the HRM on to see what happens when I get the energy surge feelings. Well, as normal whenever I increased the speed or incline my HR would gradually increase and I would feel more fatigue. What is strange is after some time my HR levels out and then eventually drops about 10 beats at the same time I get the energy surge feeling. I can then increase the resistance and my HR stubbornly holds around the lower rate and I no longer feel any fatigue unless I get aggressive with the difficulty. Not sure if I should get this checked out. |
