Welcome
@yuirlandi .
There aren't any resources on DAREBEE named after superheroes anymore due to trademark law. You can read more about that here:
https://darebee.com/faq/superhero-workouts.html but basically: if the name of a character or a person has been trademarked (which the name "Bruce Lee" has been), third parties cannot legally use that name unless they pay licensing fees to the holder of the trademark, which are generally quite large. DAREBEE cannot afford to pay those fees. So that content all had to be renamed.
Most of those old workouts and challenges are still in the database. They'll just have new names now. If you can remember more or less what the workout/challenge was about, you may be able to find it using the site's search filters. (See
https://darebee.com/workout.html# for the Workouts search page and
https://darebee.com/challenge.html# for the Challenges search page.) You won't be able to search via the old name of the workout/challenge that you remember if it used to include a trademarked name. But you may be able to narrow down your search using the other filter options. Additionally, if you post here what you can remember about the resource you're looking for, someone else may be able to help you find it.
The running section on DAREBEE received a significant makeover a few years back in which most of the old running Challenges were removed and replaced with full Programs. You can find those here:
https://darebee.com/program.html#pty=running (including the 8 Weeks to 5K program, which may be what you're remembering). There is also a
From Walking to Running Challenge that's still available as a simple 30-day challenge.
I don't remember a Challenge formerly named after Bruce Lee, so I'm afraid I cannot help you there.
If you found the themed workouts in general inspiring, you may also want to check out DAREBEE's
Workout Collections. You can search specifically for themed workout collections on that page. These won't contain names of specific superheroes any more. But there is, for example, a
Superhero Workouts Collection now, along with some fighter-themed collections such as the
Ninja Workouts Collection and the Fighter Workouts Collection.
