I'm really far behind after spending a good part of the spring and summer unable to hike due to plantar fasciitis. I seem to be over it now but am working up very gradually to avoid re-injury. Both I and my dog (almost the same age when you consider that 1 dog year = 7 human years) are really out of shape! We have finally worked up to one mile.... At least my achilles tendons are very flexible thanks to all the stretching I've been doing for the plantar fasciitis!
