I almost forgot to give a quick update on the Liquid Grip product in the race after my earlier review!
I used it twice- Once before the monkey bars and once before the final wall. The grip was simply amazing. Even though the ropes and bars weren't wet or greased as they have been previously, I could fly up and across both obstacles with ease. Not necessarily faster, but with less effort.
I need to practice getting the Liquid Grip on to my hands whilst running with more efficiency, but I'll get there. In the meantime I can confirm that this product is great for obstacle running! :-)
