Additional features include historical progression and veteran leaderboards, age-group analysis, a Vasaloppet seeding estimator based on qualifying race results, a pacing calculator that recommends checkpoint targets, and a race planner with expected times and cutoff margins for selected start groups. vasanerd states that it is not affiliated with Vasaloppet or Birkebeinerrennet and that its data comes from publicly available race results.
