FIntastic reviews

See what our fishy friends have to say about our events!


I have run many races in many places and I have to say, the Mudcat Marathon is now in my 'faves' list for SURE! This race was absolutely incredible with the unforgettable scenery, the efficient and friendly volunteers and the SWAG!!!!! Well done Sheryl and gang. I cannot WAIT to tell everyone I know to sign up next year.

Simply fantastic! I will see you next year! It was well organized, great volunteers, the medals are incredible and the scenery on the course was beautiful!

This was such a good experience. The course was beautiful. Race director was incredible. Very responsive and supportive. The start at knights beach was perfect for prep, getting to know some fellow runners and just getting ready in a nice environment with indoor washrooms!! Volunteers and staff were everywhere throughout the course. The layout with full and half meeting up later with the 10 and 5 was really unique. Thank you again for making this such a rewarding experience and memory. I highly recommend!
