Small thing but maybe the swimmers out there can relate. Discovered today that I've been doing breaststroke wrong for the past 40 years!! After realising that I have a very high stroke rate, I did a bit of reading. Tweaked my glide phase (quite radically) today and knocked 20 strokes and 30 seconds off my 100m. 🏊♀️ Would like to go back in time and have a word with my school PE teacher, who I've just found out wasn't just a mean bully, she was also very wrong. 🐬
