I plan to ride the Fireweed 400 here in AK this summer. 400 miles 28,000 ft total elevation gain. this will be my first really long ride (more than about 80 miles). looking for any tips/trick or ideas for training, food or otherwise. I plan to spend a lot of time on a bike and do some hill climb races as training. the longest training ride I plan to go on will be about 130 miles. Any input would be appreciated.
