If you are into quality rather than quantity running, then the two races are definitely too close for you. I am doing 3 full marathons in 70 days. But quantity is more important for me than quality. I know runners that run about 20 to 30 marathons every year. I say, go for it! Just treat the 2nd marathon (SCHKM) as a LSD and you should be fine. BTW, if you do one more before March 3rd, you are also eligible to join the infamous Marathon Maniac club. Check out Maniac #1 Steve Yee (an American Born Chinese), he averages 50 marathons per year. Another member Norm Frank ran more than 900 marathons in 20 years ! I too will be eligible to join the MM after the Honolulu trip in December.
Too bad they have to suspend the game. They should not have even started the game if the weather forecast predicted rain during the game. Bad!
