This is purely a running question, but I've lurked around here for a while so I'm hoping I could get some help.
Currently I'm training for a marathon, and I'm participating in a local race series as a part of my training. I take the long races around my projected marathon pace (8 min mile), which leaves me a bit of energy towards the end of the race. I like to ease into a sprint in the last 300 meters to see how fast I can push myself over the finish line. However, I'm starting to doubt if I'm being respectful to the other runners.
This isn't a charity race, but considering I'm not hanging around the "competitors" I was wondering if I was being rude by sprinting past the people I was running next to for the past hour.
