SO here we are, 4 weeks to go before the Ultra 100k in Mongolia. Big training run coming up on Saturday - 12 hours. Last effort was 7 hours and I only managed 42k, though it was hot, humid, and on rough sandy and narrow rocky trail. I need to do at least 60k on Saturday. Mentally that is important.New shoes seems good, now all that remains is to find somewhere to run for 12 hours in Phuket!
