Well we did it. Rented 2012 Specialized Allez from The Bike Shop on S Kings St in Honolulu. Picked up the bikes on Monday evening....set out around 7:30am. We did a counter clockwise loop from Hawaii Kai up through Kailua (sp?) and to the North Shore. Here's where it got a little squirrely for us. My phone died because of apps I had opened...only got about 60 miles recorded on Strava...we relied on very sparse gps signal from Haliewa (sp?) back to Honolulu. There was a 3 mile stretch gaining about 1000ft of elevation...believe me, after having the wind to our back for the earlier part of the ride,...this 3 miles was tough!
But nothing compared to trying to find our way back to S King St and avoid highways....which we did end up on a few times...THAT WAS SCARY!
So glad we picked up the bikes the night before, because we probably wouldn't have made it before we lost day light.
All in all, I think we logged in just over 100 miles...so that was MY VERY FIRST CENTURY ride.
It was a great experience and if you have a chance to rent from The Bike Shop ... they were great! And very reasonable...it only cost us $40 per bike for the day.
