Can I ride an e-bike? Yes, we love e-bikes, but with a few rules
You must be self-sufficient, meaning MGF will not provide SAG support for these bikes. If you plan to ride an e-bike, please make sure your route choice is appropriate for your battery life. If you choose to do the Gran Fondo, please note that 70+ miles of this route is closed to vehicles and our support staff will not be equipped to help you.

What roads are closed? The closure starts on Highway 120 just after the turn off to the Rufa towers and continues until Browns Campground on Benton Crossing Road. The closure is in effect from 8am until 1pm. There could be some light vehicle traffic on the road with law enforcement, SAG vehicles, and other vehicles not subject to the "thru" road closure.
Can I start early? Riders who start early will not be timed and will not appear in the results. Early riders also run the risk of rest stops not being open, meaning they could potentially be unsupported for the duration of their ride depending on their speed. We DO NOT recommend starting early.
Will there be something to eat and drink? Yes, tons of great selections including a light lunch at the Black Lake and Watterson stops! Every rest stop has something special.
Will there be any Gluten-Free foods at the rest stops and after-ride meal? We make a concerted effort to accommodate our gluten free riders! Each rest stop will have a GF items. We will also have a Gluten Free items available at the post ride party - please be sure to request when getting your meal.
I want to bring my dog to the event. Do you offer dog sitting services? We have partnered with Sierra Dog Ventures who provide fantastic dog walking services and adventure camps for your dog!

We like to use old school communication! If you need assistance, please tell another rider to send the message up course or flag down a support vehicle. We ask our riders to be team players and always willing to help out others.
Are my ride pictures really free? They really are free! No matter which ride route you are doing, we'll have photographers at several locations on the course taking your picture. You will be able to download digital versions of your pictures at Captivating Sports Photos' website within a few days of the finish.
What are the finisher gifts? We change up the finisher gift every year - they are always awesome. They will be distributed as riders cross the finish line.
What will the weather be like and how will it affect my ride? Mammoth Lakes and Mono County is often beautiful, but can be challenging too. You will be in the big mountains at high elevation so you should come prepared for anything from cold mornings in the 40's to warm afternoons in the high 70's. Rain is possible and wind is almost always a factor to some degree as it is with almost any bike ride anywhere at anytime. Have the conditions been challenging some years - yep! Have they been spectacularly beautiful other years - definitely!
