My training has been less then stellar recently. But I planned a long run for this morning to try them out. Normally before a run I'll have coffee and a piece of toast with peanut butter. I skipped the toast and the coffee as we had no milk in the house (inconceivable). On to the energybits. I took as directed. Swallowed whole with some water. I took them in groups of 5. Seemed like there were more than 30 in the pack, but I didn't count. Then off I went. My stomache felt full during the run (in fact it still does 1.5h later). Only felt uncomfortable when I had some burps that definitely were 'green' in flavor.
Unfortunately I didn't sprout wings to power me up the hill at km 9, but I made it farther up the hill than I did a few weeks ago.
Not sure if it really affected my performance. I did have a faster pace, but that could be from the fact I didn't run all week.
All in all a positive experience. I'll try some more at a race in 2 weeks and see what happens.
