This is a simplified version of the logo you could use this version in instances that require embroidery and the other in times when conventional or digital printing is used.
I also like this idea because of your slogan, when doing distance running they ring a bell on the last lap. To have run a good race you need to start with the end in mind and finish well. But then you know this better then I.
Plus, in boxing, one has to answer the bell. The main use will be for print, business cards, flyers, etc. I like both #7 and # 16. I like the font of the start strong/finish strong on #16.
