How long will this affect you? It could be days, it could be months - there are a lot of factors influencing this. My advice, if you are planning on an October marathon, is to stop running now and compensate with activities that don't aggravate the Achilles.
When things have improved a little by taking the load off the tendon the usual approach is to add in an eccentric strengthening program. This usually sorts things out but some some injuries are resistant to these methods.
So back to how long, my wife had the condition after a 20 mile walk. She was recovered within about 10 days. My last run was April this year. Nothing has shifted the problem this time around.
