We should not call it a bull run. These are just some small rallies bitcoin made to create FOMO. Mostly done by exchange to liquidate future traders who open their position with high leverage.

Usually bull run start 3-4 month following the halving. In a bull run we don't see a major correction after rally. Bitcoin rallies and then little bit consolidation and then again rally. This continues till bitcoin cross its previous ATH and made a new one.[/list]
