so i hear that if you are seventh day or whatever that one religeon is where you cant compete on saturdays, you have the option of running on friday and then your time will be added into whatever division you are in on saturday once the race is over. this goes for any division. so basically you can run in perfect conditions on friday with someone right next to you, then on saturday someone could run in the rain win easily jogging through line but end up losing once the times from saturday are added into the mix.
