I'm currently experimenting with CoreCtrl having recently introduced it to my heat training, so early days of using CoreCtlt but so far the results are very encouraging. The main reason for experimenting with CoreCtrl is for the Everesting World Championships on Mt Etna in September where temperatures will be mid to high-twenties.

I used the CoreCtrl-cooling system the week leading up to Swansea 70.3 Ironman race, which had temperatures in the late 20’s early 30’s on the day, I was very impressed with my performance in the heat, which I truly believe the cooling system had a big effect on me especially on the half marathon at the end!
I will definitely be taking these to Kona with me in October.

I used the CoreCtrl specifically to target an indoor cycling race which was taking place during a heatwave. I felt much more in control than in previous hot races. The sachets were easy to take and my HR on the bike was much lower than I've previously seen in hot conditions. I'll be buying again!
