Sometimes it's easier to run. Especially if there are people chasing you who want to capture or hurt or kill you. And especially if these people are stronger or greatly outnumber you and to face them is to give up your life or freedom. In these cases, it's a lot easier to run.
But taking the easy way out is not always the best solution. Living a life on the run can be stressful and demeaning. There comes a time when a character grows tired of running. They decide to stand their ground and fight (or surrender in some circumstances) even though the odds of winning are slim. This can be portrayed as very brave, very stupid, or both. Still there is no denying that there is something admirable about a person choosing to face their fears. Notably, it works a lot of the time... but not always.
Sometimes it may not be the enemy that the person is fleeing, but destiny itself.

In both movie and book of Howl's Moving Castle, Howl admits to Sophie that he feels this way. In the movie, it works out well for him. In the book, it doesn't at first, as he goes completely in the opposite direction and becomes a bit too aggressive for his own good.
In One Piece, Usopp, Nami, and Chopper all have moments like this in their solo battles (Usopp vs Choo, Nami vs Miss Doublefinger, Chopper vs Gedatsu). Though the exact circumstances differ, the main point is that they're tired of being The Load in combat, and are going to kick ass, which they do.
Fauna in DC Nation makes "no more running" part of her superheroing motive. She may be too much of a Granola Girl to ever be entirely comfortable with vigilante work, but the alternative of being afraid of her shapeshifting and looking over her shoulder all the time for Luthor is even less appealing.
Friendship is Magic: The Adventures of Spike: At the end of the "Spike: 20% Cooler" arc, Spike is being chased by some Diamond Dogs when he comes to this conclusion — he's sick of always running from danger and needing others to save him, so he decides to stand and fight.
Surge of the ''New X-Men': "No. This has to end. We have to end it. Forty-seven of us are dead. Jay is dead. Max is dead. Laurie is dead. Brian is dead. John went insane, and who knows where Kevin is. The X-Men can't save us. The O* N* E and their Sentinels are a sick joke. They'll probably be coming after us next. And the Avengers don't care. It's up to us. The X-Men are half a world away. We can't wait for them. Forge could still be alive, and if he's not, then Nimrod is coming for us next. This thing was involved with Stryker. It helped him kill our friends. So we'll save Forge. And we'll take this thing down." They then go out and beat Nimrod by forcing it into a temporal paradox by overloading the time device.
The Matrix: Throughout the movie, Neo is repeatedly told that anyone who has fought an Agent has been killed, and that he should run away from them. He follows this trope (without actually saying anything) in the subway station when he decides to stop running from Smith, turning and fighting him instead. He actually manages to defeat Smith, but defeating an Agent is meaningless, as Smith simply body-hops to another person, so Neo ends up running away anyway.
Enough: Slim spends most of the movie running away from and trying to escape from her abusiveImplacable Man of an ex-husband Mitch, but finally gets sick of running and decides to fight back.
Star Trek: First Contact: After the Borg invade the Enterprise, Picard refuses to engage the self-destruct and evacuate the ship.
Picard: We've made too many compromises already, too many retreats. They invade our space, and we fall back. They assimilate entire worlds, and we fall back. Not again. The line must be drawn HERE! This far, no further!
It turns out to be a subversion: Instead of a rousing fight and the destruction of the Borg, Lily openly compares Picard to Captain Ahab, convincing him that he's obsessed with gaining revenge on the Borg for assimilating him earlier, and he decides to evacuate the Enterprise and blow it up after all.
In "Centurion", before climax skirmish with the Picts. Dias even says "I don't know about you, but I'm tired of running" just before Lock and Load Montage.
In Jumanji, Alan spends most of the film running from manhunter Van Pelt. Towards the end of the film, Alan is held at gunpoint by Van Pelt. When asked why he doesn't run when given the chance, Alan replies his father always told him to face his fears. Ironically Aptly, Alan's father and Van Pelt are played by the same actor.
Likely more a case of layered meaning than irony given how Alan, as a child, found his father quite intimidating. He's not only standing up to Van Pelt here.
The hunter from the darkest wild makes you feel just like a child... The resemblance was quite intentional.
In Apocalypto, once Jaguar Paw reaches the forest while running from the bad guy Mayans, it's Took a Level in Badass time: "I am Jaguar Paw. This is my forest. And I am not afraid."

In 'The 13th Warrior' Helfdane the Fat, one of the older warriors, has been wounded while fighting deep into a cave system with no apparent way out except for through the horde of neanderthal-like 'wendol' chasing them. He staggers at one point, then gets back up and says to the protagonist: "I've run about as far as I care to. *coughs up blood* Run along now, little brother. *spits blood, smiles* Today was a good day." Offscreen and read between the lines; he then holds the thin passageway for as long as he can before he dies.
Barely heard, just below the sound of the dialogue in the very next scene, you can hear Helfdane shouting, some weapon on weapon metal-crashing, and finally, a scream as he is killed.
In The Lord of the Rings: The Return of the King Aragorn gives this speech to Sauron through the Palantír, setting himself up as bait in the hope that Sauron's distraction will allow Frodo to complete his mission.

When Gibbs argues that it's time to embrace "that oldest and noblest of pirate traditions", Jack of all people declares that he's "never one for tradition." It probably helps that he knew that the Dutchman had a different captain by now.

Halfway through the scene he caves, points out that his gun doesn't even have any ammo... and then they hear soldiers entering the house. Bluntschli tells Raina to hide her eyes, as it'll all be over in a minute - but of course she has a wild bout of heroism and finds a way to hide him.

Rincewind had always relied on running away. But sometimes, perhaps, you had to stand and fight if only because there was nowhere left to run.
Discussed, to some extent, in Tom Clancy's Clear and Present Danger. The situation: an American special forces squad is being pursued by a 200-man army of druglord enforcers, who are well-armed but of questionable fighting quality. At one point during the pursuit Chavez, the POV soldier, wonders to himself why they don't stage an ambush or two on the pursuing soldiers, when the pursuers were still operating in small groups. A few well-placed ambushes could've broken the mercenaries' morale, whereas continuing to run could only bring in more reinforcements on the mercenaries' side. Later on, they do stage counterattacks, but by that point it's too late to heavily affect the mercs.
Katniss: Life in District 12 isn't really so different from life in the arena. At some point, you have to stop running and turn around and face whoever wants you dead. The hard thing is finding the courage to do it.

Although we haven't really seen her much while she was on the run, and she didn't seem to have one specific enemy she was fleeing, Vala Mal Doran of Stargate SG-1 does this. Daniel later explains this choice to her when she has amnesia:
Daniel Jackson: If I let you go, I know you're going to make yourself disappear. You've been running so long, it's almost second nature to you. You don't remember it, but you made a decision to stop running. It's over. Now it's time to come home.

The quarians are a people who lost a Robot War to their own creations, and have spent the last three hundred years wandering, nomadic. Admiral Shala'Raan reveals that there's a growing movement among the fleet to return to the homeworld and fight - even though as things stand that would be suicide. Depending on the order you played in, this may come across as unnecessary after Legion explains that the geth would be happy to let the quarians return... if they'd stop attacking them.

Of course, Lance can have a choice of running away again by pressing right first or by pressing left twice, but that would only waste more time in endless chasing. The solution? Lance has to move left once, and then right, in order to show Fritz and Neurosis that our hero is tired of running away, then makes a Badass Arm Fold and a Take That Kiss to show that he is not afraid and is ready for one more challenge that awaits him.
