I have done my LSD run for 30km on last Saturday. It started the running at 6:30am and finished at 10:00am. I supposed to run 35km but due to the hot weather, I quited at 30km. Overall, I am feeling ok with the 30km run and I can have another 1hr swimming on Sunday. The only problem that I have is the hot weather and the cushining effect of my shoes is not good and I started to feel pain at the bottom of my feet after around 25km running. I think I must buy a pair of new shoes for LSD with better shock absorption. But one interesting thing is that I feel painful at the bottom of my feet last time when I just finished 15km running but this time it started at 25km. If there is more training, will this pain cease? Also, I have brought with myself some candies with glucose. I took some when I felt tired. It works but whether it is common to take glucose candies during running. I thought it is easier to bring candies with me than the bags of power-gel.
Hi kopo hing,
Congrats on your long run! You know back in the old days before power bars were even invented, we all used candies or fig bars as fuel. Nowadays, glucose (monosaccharides or simple sugar) is mostly used for emergency purpose only, it is not recommended to take it regularly during LSD. Why? Because of the tendency of runners getting what we called SUGAR CRASH. That is when your body is out of glucose and all of a sudden a rush of glucose goes inside your blood stream causing the brain to trigger a signal to the pancrea to release a bunch of insulin to neutralize those glucose at a speed causing most of the glucose inside the blood to disappear fast. The end result will be more tiring (especially during running) and drowsy. So instead of giving you more energy, it is the opposite around. If you don't like carrying gels, how about those Cliff Shot Bloks or Sport beans? Have you tried any of them?
Also, you may want to try to switch to another pair of better shock absorption shoes and see if it helps. Good luck!
