Comment on TrailRunner

This really needs multithreading or some kind of optimization....with a year's worth of workout data -- which doesn't slow down Ascent or Garmin Training Center noticeably -- TrailRunner is crawling, beachballing for 30-40 seconds at a time, making the app practically unusable. I tried it about 6 mos. ago & had lots of performance issues....trying it again, it doesn't seem anything has really improved.
