My first ever 10K race will be the Bayou City Classic on March 11th, 2006. If you are a member of the Houston Striders, you will get $15 re-imbursed to you. In fact, if you join the Striders (annual dues $20) you will get 4 races re-imbursed a year. This more than off-sets the cost of the membership. I encourage you to join.
Added bonus. HARRA members also receive $2 discount.
