Don’t expect these to be easy. Don’t chicken out either – our youngest finishers are a 4 year old for the 5k and a 10 year old for the 10k. The 1/2 Marathon is two modified loops of the 10k Course and the marathon is four modified loops of the 10k Course. The marathon course does have a 9 hour time limit and a 7 hour cut off for getting through the 3rd loop. The course is almost entirely sand. Roughly 1/4 mile is paved road and another 1/4 mile is packed gravel…the rest is sand. The elevation gain is very moderate, but it’s sand trails and sand dunes so expect to feel slow.
