There are several - well depending on how you see it - portions of the ST that allow for a comfortable, more than doable 100-plus days. I averaged about 96 , with lay over days, and finished in 45. At no point did I feel like I was missing anything or going too fast, or was too rushed at one point or another. It's an adventure, which means a 1000 different things to 10,000 people.
If you go 1 mile, or 100 per day - just make sure you go and ENJOY it.
