The good news: we will see Catherine the Great race this month.
The (kind of) bad news: she will not go for no. 5 in Boston but race London six days later.
Speaking about that no. 5: while Hall will hopefully be a contender for the win (nice Interview here), our odds are on another Boston regular.
Robert Cheruiyot might be one of the most underrated marathon runners. He made his name by winning Boston again and again (and maybe also for that freak-accident-win in Chicago) but there was always talk about 'a weak field' with London being around the same time and putting (a lot) more cash on the table. Now people talk of a weak field in Boston again, only to say it could be an easy win for.... Ryan Hall!
You've got to be kidding me.
