Nothing will help as much as time on your feet though, so get out there.  I had the same downhill issues (still do to a degree) and I did Tiger Claw VERTual in May on an insanely steep trail (1800 feet in a mile) which ended up helping a good bit.\r\n\r\nPoles help more than you'd think, they saved at least one fall for me on that run.  And as others said, keep your eyes out in front, not looking at your feet.","subreddit_name":"ultrarunning","author":"gl21133"},{"body":"Hal Koerner's Field Guide to Ultrarunning (https://www.amazon.com/Koerners-Field-Guide-Ultrarunning-Ultramarathon/dp/1937715221) is solid. I bought it as I was getting interested in ultras, and I've come back to it a lot over the past two years. They might have it at your local public library if you want to sample before you purchase.\r\n\r\nGood luck on your 50k!","subreddit_name":"ultrarunning","author":"jaseman2000"},{"body":"I too agree with /u/DieRunning. I would only add you could always pick up Hal Korners book, Field Guide to Ultrarunning.
