PR by 10 seconds over my 2006, 45 year old time!! For this course. Gu around 4m, 8m, Pomegranate Stinger gel around mile 12. Carried raspberry zinger tea the whole way. Feet and right back of hip got a bit tight around 10m on. eventually found a way to use left outer hip more and immediately started feeling more evened out again. Alternate breathing was helpful throughout. Shortened stride a few times in later miles to stay up with others and pass them.
