I would run the batteries down after the race, but I race weeknights and can't hang around for that long... nor do I think the employees want to hang out that late. Maybe I just need to get a charger with a better discharge rate.
What are you running now? 5000 25C? I'd say don't go down in capacity. You might consider 5000's with more than 40 C just for better performance. While it is best to run your batteries back down to 3.85V/cell when you are done using them, it really isn't that critical. Anything less than fully charged is safer and better. So if you are down below 4.0 volts per cell then that is probably ok. Most chargers do not have a very fast discharge rate. That is because you need a physically big load resistor to have a high enough power rating. They don't fit in the compact chargers. Some chargers support using a larger external resistor. My i306 for example has this feature. But choosing the resistor and doing the required wring is a pain.
You might consider one of these dedicated dischargers
