How do I add runners data for old blog posts?

Hello. I just found this plugin and it seems like it is the best option to add statistics to my blog. I have been using my blog to enter my runs for many years, but i have not put them into statistics before. When I added runnersblog is seems like I have to create new posts in the run format to get the plugin to get them into the stats, but there is a section for runners data also in old blog posts, but if I enter anything in that it does not get included in the statistics. How do I get data for other posts than RUNs to appear in the runners_log_basic ?
