Hi Gabe,
You have 40 weeks to train for Leadville 100. With this much time I recommend adding a speed and power training plan after your Base plan to increase your performance. Start with your Base plan, take a week off then continue on with the Build peak and race plan. Then take another week off. Next start the 100 miler plan at week #1. Follow this plan until the week prior to your 12-hour race. On that week, jump to week 11 and race week follow week 12. Take a week off after your 12 hour race. Then return to the 100 miler plan, scheduling week 12 to fall on Leadville 100 race week.
