Ratings & Reviews for the Grand Lake Marathon

5 Stars from 1 Reviews

review of 2014 Grand Lake Marathon.   

5 / 5 Stars


Race is literally 26.2 miles around Grand Lake. It is a very flat course. Some parts of the race are boring (one spot smelled very farm like). There is a long stretch around mile 17 that is nothing but farm land (still very flat) Plenty of water/gatorade stops - one every two miles. Each station very supportive, cheering and dressed in costumes. No traffic to worry about. Start and finish at same location.

Race Tips

This race does have pacers. Pace groups were in 10 min intevals. Race started in the 50's and warmed to lower 70's by finish. Course is very flat and fast. I would recommended starting and staying consistent with pace.

Logistical Tips (Hotels, Restaurants, Parking, Discounts, etc.)

I would recommend booking hotel early. Celina is a very small town. I stayed at the West Bank Inn (capacity of 14 rooms) but Perfect location!! Once we parked I never started my vehicle again until I was leaving. Wonderful italian restaurant that shares the same parking lot. The starting line is walking distance. And an absolutely beautiful view of the lake.
