Back when I was young and a hiker, I found that it was always my calves that hurt the most durning a workout, and my thighs that hurt the day after.
Especially after I added hills/incline or distance. the calf just takes so much of that, if you are going up or down more than you did, that might do it.
take with a huge grain of salt, but i would say try this new pattern/path you are doing for 1-2 weeks, and see if it gets better. If not, maybe check with a doc or physio type person.
