Narrative:

After run-up on tarmac; after confusing instructions; crossed edge of runway 26L going to runway 26R via taxiway. ATC (tower) then requested my phone calling tower; and criticized me for crossing edge of runway without a clearance; which is the only way to get to the taxiway. I think my mistake was not talking to ground before moving the aircraft after run-up; even though the controller did not clearly tell me where to do the run-up. There was no traffic; however; it was an active runway. No traffic visually or on TCAS in the air or on the tarmac. Runway and tarmac contiguous; and markings very poor and weathered severely. To control the airport in this area; better markings and more help and warnings from the ground controller to advise pilots of the proximity to the runway 26L before the taxiway to 26R. Clearer instructions for run-up area would also help.

Title: AN SR22 PILOT EXPERIENCED A RUNWAY INCURSION AT PUB.

Narrative: AFTER RUN-UP ON TARMAC; AFTER CONFUSING INSTRUCTIONS; CROSSED EDGE OF RUNWAY 26L GOING TO RUNWAY 26R VIA TAXIWAY. ATC (TOWER) THEN REQUESTED MY PHONE CALLING TOWER; AND CRITICIZED ME FOR CROSSING EDGE OF RUNWAY WITHOUT A CLEARANCE; WHICH IS THE ONLY WAY TO GET TO THE TAXIWAY. I THINK MY MISTAKE WAS NOT TALKING TO GROUND BEFORE MOVING THE AIRCRAFT AFTER RUN-UP; EVEN THOUGH THE CONTROLLER DID NOT CLEARLY TELL ME WHERE TO DO THE RUN-UP. THERE WAS NO TRAFFIC; HOWEVER; IT WAS AN ACTIVE RUNWAY. NO TRAFFIC VISUALLY OR ON TCAS IN THE AIR OR ON THE TARMAC. RUNWAY AND TARMAC CONTIGUOUS; AND MARKINGS VERY POOR AND WEATHERED SEVERELY. TO CONTROL THE AIRPORT IN THIS AREA; BETTER MARKINGS AND MORE HELP AND WARNINGS FROM THE GROUND CONTROLLER TO ADVISE PILOTS OF THE PROXIMITY TO THE RUNWAY 26L BEFORE THE TAXIWAY TO 26R. CLEARER INSTRUCTIONS FOR RUN-UP AREA WOULD ALSO HELP.
