Great long run. Sticking to strategy of long and slow to build endurance. Didn't know for sure I'd do the whole 10k, but it worked out well. Had light-ish supper and took one Mentos for sugar kick around 6k mark. Seemed to do the trick, but not sure it was necessary. Left kneed started to hurt a little over the final 2k, but no sharp pain. Final 2k also fastest, but was holding back trying to stick to strategy.
