This thread is an interesting look at the different forces in play within the sport of track & field. There are some valid points made in favor of lowering and tightening the OT standards, but ultimately I have to say that those in favor of having a mass participation OT marathon simply don't get it.
The problem with 'professional' runners is that nobody wants to invest in (pay for) anything. Track access, coaching, massage, entry fees, you name it. Now we have entitled, developmental (not even sub-elite) athletes that want access to an Olympic Team selection event?
Stop it. You want to race in a national caliber event? Start with Bix, Gate River, the New Haven 20k or somewhere that a RD will fit you into the budget. Once you have gained entry and travel support, invite your family, significant other, your college teammates and anyone else from the 'community' out to cheer you on. If you are good enough, race the US Marathon Championships and create some of the buzz you seek around a national championship event.
The OT marathon is not designed to provide developmental opportunities and entertain people with the scope and size of the field. Developmental opportunities take place at the scores of events held every year for road warriors to prove their mettle. If fans wanted to watch 2:20 and 2:40 marathoners in the streets, the US championship event would have the course lined year after year, but that is not the case.
Do most fans remember where Serena Burla or Bobby Curtis ran their qualifying times for the recent WC marathon? Of course not, because we were not following closely enough and never will. We all remember Shalane collapsing into Amy's arms because they came top 3 and made the Olympic Team, in LA and in front of TV cameras. That is the purpose of the OT event: Team selection and TV ratings.
When major league teams allow local talent to take BP at the World Series with the pros, and when rec league all stars are allowed to shoot around before NBA playoff games, then we can also claim that the presence of 50 or 100 more runners at the meet hotel, in the technical meeting, on the start line and on the course aren't a distraction to the athletes with a true shot to make the Olympic Team.
In the meantime, the 2:25 marathoner looking to crack 2:20 can continue to provide the inspiration you cite, but that is not a professional endeavor and has no place at the Trials.
