One adventure could be that they find an ancient, lost spellbook. But this spellbook is guarded by magical traps. They have to use their combined knowledge of magic, Ron's strategic thinking, and Harry's bravery to get through the traps and unlock the secrets of the spellbook. Along the way, they might learn new spells that help them in their journey to clear their names or fight against whatever made them run away in the first place.
They could have an adventure where they stumble upon a hidden magical creature sanctuary. They might need to help protect it from poachers or some other danger.
Maybe they end up in a Muggle town by accident. It would be really funny to see how they try to blend in and use their magic without getting noticed. They could get into all sorts of comical situations like accidentally making things float in front of Muggles or trying to use magic to fix Muggle technology. And all the while, they are also on the lookout for any threats from the wizarding world that might be following them.
Well, it could be about them running away to avoid some dark magic threat at Hogwarts. Maybe a new dark wizard has emerged and they don't trust the school's ability to protect them at that moment.
In fanfic, one reason could be that he might feel constantly in danger at Hogwarts. With all the dark forces targeting him, he could think running away is the only way to keep his friends safe. For example, if Voldemort's followers keep infiltrating the school, Harry might feel responsible and decide to leave to draw the danger away from others.
Maybe they run away because they are tired of the constant danger at Hogwarts. They've faced so many threats, and they just want a break. So they run to a peaceful place where no one knows them.
Maybe for love. They might have fallen deeply in love and want to be away from the prying eyes of the wizarding world.
In a 'Harry and Hermione run away fanfic', they could be running away from the pressure of their pre - destined roles. Harry is always seen as the 'Chosen One' and Hermione as the brilliant sidekick.

They might travel to different wizarding schools across the globe, learning new spells and making new friends outside of Hogwarts.
Ron Weasley, whose full name was Ronald Bilius Weasley, was the second male lead in the Harry Potter series of famous fantasy novels by British female author J.K. Rowling. The sixth son of the pure-blood wizards Arthur Weasley and Molly Weasley (formerly Prewitt), he was born on March 1, 1980 and grew up in the Wizarding community, with the fiery red hair and blue eyes of the ancient pure-blood Weasley family. In the movie adaptation of the Harry Potter series, it was played by Rupert Grint. At the age of eleven, Ron entered Gryffindor House and became good friends with Harry Potter and Hermione. In the battle to protect the Sorcerer's Stone, he led Harry and Hermione through a giant chess game and won the House Cup. In the second year, he and Harry ventured into the Forbidden Forest to find the entrance to the Chamber of Secrets and rescue Ginny, winning the School Achievement Award. In the third year, he and his friends helped Sirius and Buckbeak escape from the Ministry of Magic. In the fourth year, his friendship with Harry was tested by the Goblet of Fire competition, but they eventually rebuilt their trust. In his fifth year, he became a Gryffindor prefect and was selected as Keeper of the Quidditch team, and Gryffindor won with his excellent performance. In his sixth year, he continued to be Keeper, and his relationship problems with Hermione affected the game, but he finally recovered his confidence with Harry's help. In the seventh year, he supported Harry without hesitation, embarked on a journey to find and destroy Horcruxes, successfully destroyed the Horcrux gold locket, and helped Hermione destroy the other Horcrux, the Hufflepuff Gold Cup. As one of the main characters in the Harry Potter series, Ron was ranked third on IGN's "Top 25 Harry Potter characters" list.

He was humorous, brave, and kind. His image and character had a profound impact on the film industry, the Internet, and social media. He was one of the classic representatives of popular culture. Harry Potter and the Order of the Phoenix is not enough. Please click to read the novel!
One possible reason could be that he feels unsafe at Hogwarts. Maybe there are threats from dark wizards within the school that the teachers are unable to fully protect him from. Sirius, being his godfather, represents a safe haven.
Maybe he wants to escape the constant danger in the UK wizarding world. Voldemort's followers might still be a threat even after his defeat, and France could seem like a safe haven.
She was the voice of reason. In many situations where Harry and Ron might have rushed into things impulsively, Hermione would stop and think, and guide them to make better decisions.
Perhaps in the fanfiction, Harry Potter runs away from Britain because he is disillusioned with the way the Ministry of Magic operates. There could have been a major event where the Ministry fails him or betrays his trust. Also, he may be seeking a place where he can explore his magic without the constraints and expectations that come with being 'The Boy Who Lived' in Britain.
