For someone who has run marathons before and may need a bit of a challenge, the Grandfather Mountain Marathon may be the perfect choice. Held annually in North Carolina, this marathon is definitely not for beginners. The 25-mile track offers quite a challenge.
The Grandfather Mountain Marathon has runners racing up the mountainside to an elevation of 4,279 feet. A race such as this requires extensive pre-training and probably a good amount of prior experience running mountainous races. The Grandfather Mountain Marathon has strict time limits. Therefore, runners must be certain they can finish this race.
Because this is an extreme sport, it's also going to require some extreme footwear. Running shoes for a mountain adventure should also be equipped to handle trails and mountainous terrain. Look for a durable, but lightweight design with good traction, cushioning, bounce and flexibility.
Footwear is not the only thing to pay attention to in a marathon. Clothing is also of importance. Marathon runners should be wearing clothing that will help keep them cool, as well as help wick away moisture. Clothing for running should be flexible but not loose. It also should be made of breathable fibers. Chafing prevention also is a good idea.
A good watch, as well as a compass, may be a good idea. A combination piece is even better. This way if you accidentally get off track, the compass and a good map of the location can help you get back on track. The watch, of course, will let a runner know how they are doing on time, such as whether to maybe slow their pace or pick it up some to finish on time.
Some runners also may choose to wear a hat for sun protection. The hat chosen should be thin, as well as something that that will not fall off the head easily. Otherwise, it may be a distraction during the race. Some good, moisture-wicking running socks will also be a good idea. Gatorade and water will be supplied at various checkpoints throughout the race.
