As everyone knows, Eugene's historic Hayward field will be hosting Worlds in 2021. Major changes need to be made to the stadium as Hayward isn't currently large enough to host worlds.What ideas do you have for how Hayward can be improved? Please post them below.We got the idea to start this thread as we received an email from a UK visitor, who visited Hayward in 2014 for World Juniors and has has some concrete ideas for how Hayward should be improved for Worlds. They appear below.The views below come from "anon" or "gbcm" who has been following athletics since 1958 and involved as an athlete since 1967. He became an endurance coach at end of his running career and has spent many holidays watching major champs. He enjoyed Eugene 2014 very much and is looking forward to Portland 2016. He's interested in what others feel is necessary to turn Hayward's Field into a venue that would be fit to stage a world championship event.
