Our situation is kind of complicated: my bf & his brother will be running the 5K together, then four of us (me, bf, his brother, brother's gf) will be doing the 10K, and then me & brother's gf will be doing the half (going for the GSC). Registration this year is going to be a major pain! Thank goodness I'm only registering the two of us, rather than all four of us. I had considered doing all three races so I can go for the Triple Crown (ha, I love that term), but since this is my first time going for the GSC, I want to see how my body does with two longer races back-to-back first. Maybe I will in 2017.
