The Camino crosses the route for the running, so it is blocked before and during the bull run.
The rooms in Pamplona are booked several years in advance, and the rates increase five to ten times normal. The big albergue there, Jesus y Maria, is closed. Casa Paderborn is open. Cizur Menor fills early, and the albergues before Pamplona also fill early with pilgrims who know Pamplona is jammed.
Figure out your strategy early; pass through Pamplona well before 8 a.m., or after 8:30 a.m. to avoid the closings. There are parades some days, so the Camino can be blocked or simply impassable because of the crowds.
Look here under Programme for the daily schedule next year. It is usually posted a month or so in advance:

The festival is July 7-14 regardless of which day of the week July 7 is. The encierro is daily at 8 a.m. from July 8 to July 13.
