Hi Helen,
I recommend the following stack of training plans to peak for Whaka 100 in Oct:
– Masters 40+ Mountain Bike Base Mountain Bike Training Plan
– Masters 40+ Cross Country Mountain Bike Build Peak and Race Mountain Bike Training Plan
– Masters 40+ 50 Mile Mountain Bike Personal Record Mountain Bike Training Plan
Schedule one week off in between plans to use for extra recovery or to catch up on a missed week. Each plan is 12 weeks so 3 plans plus the 2 weeks off adds up to a 38 week training plan stack.
