Tips from Coaches

”Start off conservatively! The first mile is a downhill effort. The race day vibes are contagious, and it is easy to get sucked into the race atmosphere! Go in with a gameplan, and stick to it!” – Coach Chris Poole

”Although the course is net downhill, there are some gentle rollers on the course. Make sure to check your effort +/- 5 seconds per mile depending on the part of the course.” – Coach Chris Poole

“They say CIM is net downhill. What they don’t tell you is that the first 10 miles are rolling hills. Train hills and you won’t notice them. Don’t train hills and listen to the hype about a “downhill race” and you will be very surprised at your finish time… and not in a good way.” – Coach Jamie Spruiell
