First sprint distance tri
I'm doing my very first sprint distance triathlon in June. I recently bought my first road bike - a Trek 2100 WSD. I think I might want to swap out the stock pedals (Shimano M505 SPD) for something a bit easier to unclip out of. Of course, I realize that I would need to get road shoes. I'm currently looking at a pair of women's Shimano R099W (carbon composite sole, SPD-SL/Look, $109). Which of the compatible 3-bolt pedal systems should I consider? Any pro's or con's with any of them? I'm sort of on a budget, so it would be ideal if I could find something decent that's not too spendy (under $100).
I'm also wondering if I should invest in a set of clip-on aerobars? Seeing as it's my first tri and the bike distance is very short...I don't think I need them...but figured I would ask anyway. I suppose I could always add them on next year, if I stick with it. TIA
