I have been riding a Trek T900 tandem as captain, for a few times a year the past 4 years. I went out twice last month, which was the first time this year.
In an effort to become more active (I'm 5'8", 250 lb) I picked up a Trek 8.3DS and rode it Tuesday and Thursday this week on reasonably smooth roads (in a pretty upright position - it has flat bars) for 4.5 miles on each occasion (wearing my Bellwether shorts).
I noticed that on the second ride, my sit bones were very painful at the beginning, but not as painful by the end. However, I can tell that I am still sore a day and a half later.
The question: How long should I give this saddle before trying something else? I suspect that part of my problem is the fact that my rear is just not used to riding, but I have no idea how long that will last. Is substantial pain with this little riding indicative of a poorly fit saddle or a poorly conditioned rear? Your thoughts are appreciated!
