Week 5, Day 1: Nerves for sure

This week makes me nervous. 3 different workouts, 3 different days. Will I be able to do it?

Day 1:
Brisk five-minute warmup walk, then:
Jog 1/2 mile (or 5 minutes)
Walk 1/4 mile (or 3 minutes)
Jog 1/2 mile (or 5 minutes)
Walk 1/4 mile (or 3 minutes)
Jog 1/2 mile (or 5 minutes)

Day 2:
Brisk five-minute warmup walk, then:
Jog 3/4 mile (or 8 minutes)
Walk 1/2 mile (or 5 minutes)
Jog 3/4 mile (or 8 minutes)

Day 3:
Brisk five-minute warmup walk, then jog two miles (or 20 minutes) with no walking.
