8 days to marathon

Want to Run but Rain....what to do.....rest lor.. I suspect I tapering down too fast...is always a mental problem here that suddenly u did not run the normal mileage, you will feel your fitness going down... I only ran twice this week, 8.6km on tues and 4.3km on thurs.... Hopefully the weather permits and I can run this sunday morning...if not, I may go berserk!!!!!
