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.

Fauna in DC Nation makes "no more running" part of her superheroing motive.

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.

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.

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.
