The MGP is very inexpensive to run but modest donations are appreciated.   However in the last few races a few runners have been too generous in their donations.   A quite a few people have asked me how much they should donate?   Well I finally figured out expenses.   It works out about $1.50 per race per runner, or yearly donation of $6 if you do all the races.   Please do not feel obligated to donate, this is just a guideline and to give visibility to the group what expenses are.
