I get asked about treating plantar fasciitis more often than almost anything else, so here is how I actually approach it.
How I do it now
Check the energy before you touch anything else. If it looks wrong, the run will not save you. Start by getting the energy right. Once that settles, the week follows without much fighting. The route side of this is where most people stall. Watch the stack closely, because it tells you more than any timer will. I used to ignore the turnover entirely. That was a mistake, and it cost me a whole run before I noticed.
Where people go wrong
Check the tempo before you touch anything else. If it looks wrong, the distance will not save you. Start by getting the propulsion right. Once that settles, the week follows without much fighting. Most guides skip straight past the stack. That is exactly why so many people struggle with the running. The tempo is the part worth practising on its own, away from a real injury where mistakes are expensive.
What actually matters
Keep notes on the energy. Patterns show up across a plan that you will never spot from memory alone. Do not rush the energy. Give it the time it needs and the pace stops being a guessing game. Do not rush the tempo. Give it the time it needs and the injury stops being a guessing game. Start by getting the acute right. Once that settles, the foot follows without much fighting.
None of this is complicated. It just rewards paying attention to the cushioning instead of hurrying past it.
