Couch to triathlon plans?

22 Week Sprint Plan
"A 22 Week Program taking you from no swim, bike or run experience to your first sprint triathlon. You can also use this as a great base-builder for first-time triathletes."
Min Bike: 1.86Mi (dist) Max Bike: 19.88Mi (dist)
Min Run: 20m (duration) / Max Run: 50m (duration)
Min Swim: 91.44M (dist) Max Swim: 822.96M (dist)

This plan does not pace down the last week before race day. Would you add a 23 week with less endurance to rest before the race???

Thanks,

Laura
