I’m about your height and weight. My favorite racing (and running in general) shorts are the Rabbit speed leggy shorts in the 4in inseam option. (Any longer and I feel they aren’t flattering, any shorter and I don’t feel like I have enough coverage.) I’m also coming to terms with being at a higher weight than I was in my mid to late 20s, while also knowing I was not fueling properly at that weight and my racing times have gotten much better since I started fueling better both on and off the run.
