I've started exercising again, intentionally, not only walking 10-15 miles a day without much elevation out of necessity. Did about 15 minutes of HIIT today. I figure doing that a few times a week and adding some strength training will help get rid of this flub. I need more quad and core strength. I walked up a hill the other day with only 250ft elevation gain and a light pack (like 10lbs), and I was ridiculously slow. Goal is to get at least my 14th NH48 down before leaf peeping season.
