"Derek: We’ve decided to take a different tact: Next time Frank runs one of our races there will be an official observer in place. This is a great opportunity for him to confirm his past performances and end the conversation.
Pending any additional information, this is the best solution for all. Appreciate your efforts. Best. "
Did LA Marathon not follow up? He ran their race in 2017, 2018, and 2019, yet no observer ran with him? Did he sign up late so they didn't have someone stick to him? Didn't they flag him that if he sign up, they would have someone following him?
