My name is Brian Cake, and I am the point of contact for the Tuesday/Thursday Indy Runners (IR) club runs. There are official IR runs on Saturday and Sunday mornings that aren't too far from Fishers. The Saturday run meets in Broad Ripple, and the Sunday run meets in Lawrence. Even though the weather's turning cold, you will find other runners at both locations throughout the winter.
IR is always willing to consider adding more official club runs, including in Fishers. If added, it would appear on our website which gives it visibility. (You're welcome to continue discussing non-club runs on this message board.)
The key is that there are certain expectations of any official club run. This prevents things like runs being listed on our website which simply consist of a few friends who may or may not show up to run. One of the expectations is that participants be members of IR (at least partially for insurance purposes). Another expectation is that there will be people at the runs each week.
If you would like more information, feel free to contact me. My contact information can be found at the HTML link I mentioned above.
