Here, the three of them are officially starting the marathon. I feel that they should wear matching team jackets to all events, at all times.

WILLS: GO! RUN FASTER! KATE: Wheeeee!!! HARRY: Look at that guy! He's dressed like a chicken!

There are many photos of these three blasting each other with airhorns, which is OBVIOUSLY what one does when given an airhorn. (There was another photo where Kate was blasting Harry.)

"You can blast me with your airhorn any time you want."

Aw. This is sweet. You can tell they feel very much like a team on this one.

Time to turn to Informative Caption, after I note that I don't like Harry's sneakers and I assume Meghan is going to do something about that the next time she is in London. Ahem: "[Harry, Wills, and Kate] cheering on runners at the start of the 2017 Virgin Money London Marathon on April 23, 2017 in London, England.

Later, the three of them moved to the cheering section, then to hand out water, then to hand out medals -- it was a long day -- and sincerely seemed to be having a really good time. Harry is INVESTED in people running. (This all makes sense: They're always at their best at sporty-type events.)

People who run marathons are amazing. People who run them in costume, even more so. This person has the Heads Together headband over the topmost point of his star. I feel like Wills has rarely looked more delighted.

"Is Spider-Man hitting on my wife?!" So many high fives. Make sure to look at the other person's elbow, kids.

YAY SUNGLASSES! (Also: Of course Kate is wearing one of her Breton-striped shirts under there. Never change, girl.)
