Possible Running Alternative

I am suffering from plantar fasciitis (PF). I have not run any distance at all since mid-July in order to facilitate the healing process.  I have increased my weight training,and biking (which does not seem to bother it). I tried for the first time last night a 15 min hike with rucksack and trekking poles to see if this bothered my PF. It didn't seem to harm it much. I will attempt it again later this week and see how I feel.  Living the dream.  curt
