Welcome to the area!

North Tarrant Cycling Club I think is based in Roanoke. They have a Facebook page.
They also sometimes join the Playtri Ft worth weekend ride which is pretty solid with various groups at various speeds/distances when it gets warmer (some still cycle now but group is smaller). Playtri Ft Worth probably has a tri group too. They have some weeknight rides too. If you are willing to drive a bit more, Playtri Colleyville usually has tri sessions at night (indoor trainer, runs, lifting/plyometric type stuff etc). Not sure about swimming out there. Check out local YMCA, 24 fitness, LA fitness etc.

There is a nice natatorium pretty close to you in Keller...a lifetime fitness in southlake/colleyville...there is a tri club that does consistent swims out at lake grapevine...Irontex Triathlon...they do some nice long rides going through that area and Roanoke too...there Is actually a decent climb there...for this area...

Thanks for the information. Does anyone ever ride around Texas Motor Speedway?

Also any recommendations on a good Bike Shop in the area?

Yes...lots of riders out at the speedway too...boring...but pretty safe... that tri group I mentioned earlier rides out there a lot too...there are plenty of bike shops around...everyone kind of finds their own way...What works best for me is working with James over at Fort Worth Cycling and Fitness...I have not found anyone that gives me better deals on bikes...and my favorite wrench in town is there too...Jason...but as I said...everyone has different thoughts/preferences...there are other shops closer to Roanoke...

The ride I mentioned above goes by that general area
