This is what happened after the 16K trail run. In comparison to the week before 14.5k, I finished this run stronger. I relate this to better eating the night before. Many athletes talked about Carb Loading, which is basically eating a lot of carbs the week or at least the night before your long run, mainly pasta. Other athletes revoked such an idea and talked about just having their regular healthy dinner and avoiding spices or extra fibers.
I chose to eat a lot of pasta the night before the long runs, hydrate well while running, and be mentally prepared for the run, and the latter from my point of view is more important than sleeping well, as one-night restless sleep will not ruin your run.
After finishing the run and driving back home I immersed my legs in cold water for 5 minutes, again there are different opinions regarding this technique of recovery, some say drinking and eating right and wearing compression stockings is just enough. I did all of this.
The next day, I felt pain in the upper back, maybe due to bad running form or weak muscles or maybe I am not yet accustomed to such long runs, anyways it just felt better than the week before. This means your body can get accustomed to anything with training and following the proper techniques.
The following day I did a nice 5k recovery run, which also went better than the previous recovery runs of the past weeks, and it felt good.
Today I took a rest, ate well, and prepared for my next challenge tomorrow isa, 21k as advised by my friend Salah. Pray for me.
