1. Men who swim the same pace as you in lane, unless you as a woman get in then they splash and swim just very slightly faster than you, just go you can never quite seem to turn at the wall properly as they also pause out of breath often so you can’t pace away from them. 2. Men you do front crawl in lane either super splashy, hitting you or so wide they nearly touch the ropes both sides (or all of these). 3. People who turn out on side roads forcing you to brake, then pootle along at 18mph
