About a year ago I noticed something about my running versus my biking but until today I haven't been able to do anything about it. Today I changed that. What I noticed was that in a bike ride when I hit the later distances and begin hating life I speed up considerably in an effort to just get it done. This makes a huge difference in my overall time and I can absolutely see the difference. But on the run when I start feeling bad, I slow down, I start walking more or barely shuffling. So today I went out for a run in this heat and started feeling bad at mile 3.5 of a 7.5 run. Instead of slowing down, I sped up. I didn't sprint but I pushed harder and gutted it out. The run went so much better than any I have had in a year. Mental breakthroughs may honestly be more important in the long run than physical. What do you think?
