You may remember Rachel Townsend, the teacher from Ohio who died of a heart arrhythmia after finishing last fall's Chicago Marathon. When she crossed the finish line, Rachel had qualified for the Boston Marathon, and would have run in it today, if she had survived. The Tribune reports that many runners will be wearing caps that say "Running For Rachel," and one runner will be wearing Townsend's number, so that she will end up with an official time in the race. In addition to these tributes, scholarships and memorial races have been set up in Ann Arbor, MI, where Townsend taught for seven years.
