Hello! I'm new to BRC and sought it out after suffering a fairly severe muscle strain today on the outside of my lower left leg (I actually questioned whether I had a hairline fracture in in fibia, which does not appear to be the case). Obviously, I did some things incorrectly. I have been doing 1-2 trail runs (typically 2-3 miles) for about 3 years now. And for the last 18 mos., I've been doing treadmill 2-3x/week and the elliptical 2-3x/week, with each of those workouts concluded by 20-30 min. of CrossFit training, with a focus on core/balance work. This running was do e with Nike Free Run shoes (the same pair). Since the COVID-19 scare kicked in, I've been just trail running 3-4x/week, with some CrossFit and stretching at home. I've been working with the Maffetone 180 Method to stay within my target heart rate range (~135 beats/min.) while running, and my running time this past 5 weeks has gone from ~30 min. to ~60 min. because my breathing is no longer so strained as it usually was in the past. Also, I've been doing these trail runs in minimalist trail shoes from Xero. I never over-stride, and I haven't had any dramatic twists of ankles/knees, yet here I am with a leg that can barely support any weight. So, I am definitely looking to learn more about training and technique so I can get back on the trails soon. I look forward to joining a community of like-minded, athletic nature-lovers who have learned to truly appreciate and love their running!
