Here's an example of a strategic ride plan to achieve Rapha's #festive500.
NVRC will host three rides and utilize the LSD ride on the 30th, for 60% of the mileage needed to meet the goal of 311 miles in eight days. You need to plan your remaining four days or 126 miles to get there... go big or spread it out, it's up to you.
((UPDATE: rides are dependent on weather and the status of the ride leader's cold. :-) For last minute updates please refer to the ride calendar. Thank you.))
Find others to ride with and make your time on the bike more enjoyable.
Advice: plan flat rides and stay away from climbs... you need miles, not elevation. Flat miles are quicker.
Watch for ride postings and calendar updates. Good luck!
