I'll start with saying that I came into triathlon as a runner and LOVE running. So when I realized I had PF (and eventually a tear), it was a super hard pill to swallow.
I had plantar issues begin on Labor Day 2015. I was fortunate enough to be doing a running race at the time, and there was a physical therapist on site that diagnosed me with Plantar Fasciitis. I went and saw my local podiatrist who confirmed that I had PF. I was signed up for Kona, so decided just not to run until race day and hope all of the treatment* I was doing would cure my foot in time.
I taped my foot with KT tape per advice of PTs (actually had the Kinesiotape experts at the expo do it for me!) and swam and biked. Hoping off the bike, I knew immediately I'd have issues the entire run, but was determined to finish since it was Kona after all.
Not sure if racing Kona was what caused the tear, or if it was torn prior to even running in Kona but I could barely walk for a week after. I went and saw a podiatrist (The Running Institute in Chicago is AMAZING if you're in the Chicagoland). We tried a cortisone shot at first because there was a bursa over the site of the tear that needed to be "attacked" first. Once that was taken care of, I had an Amniofix injection to fix the actual tear in my plantar... this is the newest thing, similar to PRP but the recovery time is much faster. I was able to start biking again 10 days later and was cleared to swim then as well but just chose to wait another week.
About 20 days after the Amniofix injection, I was able to start attempting a run/walk program. At this time, I also tried out ASTYM (basically Graston but for your plantar) through the physical therapist as there was still some annoyance on my plantar. When I went back to my podiatrist after ASTYM not feeling like it was working, he noticed there was basically some scar tissue, so I had EPAT/Shockwave Therapy done. 4 treatments later over the course of 2.5 weeks and I was running pain free. I also had custom orthotics made and went from wearing a shoe with support (Saucony Fastwitch and Guide) to one without (Saucony Kinvara) to accommodate the extra support the orthotic was providing. Definitely look into custom orthotics.
I had the Amniofix injection done on December 20th I believe, and was running again (easy) 2 months later, which I have been told is a faster turnaround compared to PRP. Obviously every case is different and every podiatrist will treat a tear differently as well, but hope this helped at least. Just be smart about it now or it can come back real bad!
*treatments from September 4 - October 8:
Gua Sha tools (on Amazon) with coconut oil, rolling my foot on a frozen water bottle every 2 hours, KT taping styles, night split (on Amazon, much preferred over Strassburg sock), Strassburg sock (didn't care for this, caused tightness in the back of my knee), lacrosse ball/foot roller all of the time.
