Triathalon here I come!

My friend Lyndsey has done the WunderWoman Triathalon for two years in a row now.  She has asked me both times to do it with her but I chickened out.  I never think of myself as a good swimmer and swimming in a lake with hundreds of other women doesn't entice me at all!  Today she asked me if I would do the relay with her and I agreed!  Her mom is going to do the biking, she will do the swimming and I will do the running/walking.  The course is just under 3 miles, I think I can manage that!  It's an all women's event and I'm kinda looking forward to it!
