Ten sprints, ten different styles — the Crab, the Superhero, the Giant Leap, and Slow Motion, which is far harder than it sounds. Short and fast with full recovery, which is exactly what taper week needs. Full guide for every age right here.

Welcome to the strangest week of the challenge — the one where we ask your family to do less. Today's rule: if you finish feeling like you could have done more, you did it right. Full guide for every age right here.

The longest run of all 92 days, with one rule: you never run the whole thing, you only run to the next landmark. Then a Sunday to rest, reflect, and set the Day 92 goal. Full guide for every age right here.

Twelve weeks, twelve stations, one course — the Traffic Light Game, the chalk ladder, the balance beam, the breathing, the target throw, all of it in one lap through the whole summer. Completed, not raced. Full guide for every age right here.

One event, three attempts, and one specific thing you change between them. "Try harder" is the least effective way to break a record — every one of these events has a technical fix worth more than extra effort. Full guide for every age right here.

Today's run asks almost nothing physically and quite a lot mentally: an out-and-back where the way home has to be faster than the way out. Which means running the first half slower than your body wants to. Full guide for every age right here.

You've known this day was coming since June 1st. Hill repeats, with one rule: your last one has to be as fast as your first. Hardest doesn't mean longest — little ones are done in eight minutes. Full guide for every age right here.

Day 75 of 100, and the whole week turns into a competition: throw a heavy thing, carry a heavy thing, jump, climb, balance, race. Every age has its own bracket, personal bests score points, and the victory lap has no losers. Full guide for every age right here.
