i am trying to plan a trip next spring to a spanish speaking country for a month and would like to also include a little altitude training. has anyone been/run in places like peru, mexico city, etc. I am especially interested in the running as i have been to many developing countries where running was difficult, unsafe or both. anyone have experience with this? i know that shalane et al. went to mexico city this winter, but i won't have the luxury of being hosted by german silva. anwyay, thanks, b
