I predict (based on a little knowledge from Josh Cox) that Des Linden will run Boston Marathon in 2020 and skip the Olympic Trials. This will change the way many top level Pro Americans handle the Olympics in the future. The only reason that top Ethiopians and Kenyans run the Olympic Games is because their Governments force them to. This has already happened in the World Championships where the only Americans that run are Americans that would not receive appearance fees to run elsewhere.
An athlete like Des is hot right now and guaranteed big appearance fees at NY and Boston. However, if she runs poorly at the Trials she will go down significantly not to mention the inability to run both the trials and Boston.
