Running in the Past (or R.I.P) was considered to be the spiritual successor to the IAS tournament series. Announced by Ratchet5 at the end of the call for LukeRF44's IAS 10 Grand Final post-recording, the tournament would be run in much the same way as the past IAS tournament series. The only real variance was that the winner of R.I.P will not be known as the IAS champion but instead will be crowned the first ever World Speedrunning Champion.
The tournament began on December 30, 2015, but as the days went by it became obvious that there was a general apathy to do with the tournament, including from the hosts. RIP struggled to get on its feet and was cancelled by Nintendogen64 soon afterwards.
There was an attempt to revive the tournament as just a single race between everyone who uploaded a speedrun, but this was also met with apathy and nothing happened.
