Only 3 weeks before first marathon and my plantar ligament is painful, what to do? Stop training? Run through pain only on race day? I am icing and taking OTC anti-inflamatories. Any advice will help as I have trained hard for my first and would hate to miss it.
Are you in pre-PF or full blown PF? Do you fall down when you get out of bed?
If you don't have full-blown PF, get one of the knobby balls that are sold online and at running stores and work the heck out of the bottom of your foot, don't run but cross train and see if you don't feel better.
In terms of cross training, try an elliptical. Similar leg motion, and far less strain.
If I was in your position I would consult a podiatrist - maybe it is not Plantar fasciitis. I have plantar fasciitis myself for a few months now. My podiatrist prescribed me with Custom made orthotics which did not work at all. I understood that treatment efficiency is very individual. If something works for one it will not always work for the other.
I am not training for marathon but I am running about 25 miles per week. I have found Taping very useful. Taping helps to relieve the pain, keeps your foot from getting injured again and helps you get through your daily routine and exercises. There is a good web-page explaining the subject in this informative website-
Get to a podiatrist asap. Preferably one who is also a runner. I had PF a couple of years ago and ended up with orthotics. I made it through my first marathon earlier this month. There is not a shot of my having pulled that off without my orthotics.
