Obiena resumes questMANILA, Philippines — EJ Obiena is bidding to reenter the world top 10 pole vault rankings after slipping from No. He started his drive at the ISTAF Indoor Championships, a World Athletics Tour Silver, in Dusseldorf, Germany, last night (early this morning, Manila time) with results not available at presstime. The start of the World Indoor Tour Gold for me is in Karsruhe, Germany, on Feb. 8. I’m invited to join the event but it conflicts with the Asian Indoor Championships in Tianjin, China, on Feb. 6-8. The Tour Gold has bigger points than Tianjin.”Obiena aims to qualify for the World Indoor Championships in Kujawy Pomorze, Poland, on March 20-22 and is building up points to make it.
