I am planning a trip to Vietnam and Korea Oct 7 - 19 and need information on whether there are any running groups in Seoul or good running routes around the city that would be accessible by subway. Also, are there athletic clubs or gyms that I would be able to use while I am out there? My marathon is on Oct. 22, so while I am in Asia I will need to do long runs that are around 10-13 miles. Does anyone know of any running routes or parks that I could run in that are fairly safe? I will probably want to run early in the mornings and I am female so safety would be a concern for me (my husband will be going but he is not a big runner and will probably not want to wake up early in the mornings while we are on vacation).
