I put far too much pressure on my self....just done first 20 miler LSR and was a lot slower than recent runs, and instead of thinking, 'well, LSR's are time on feet and this is your first 20 miler so it's ok', I feel like I've failed and lost any confidence. past few 18 milers have gone well, yet this one was 20secs/mile slower! Grrr.
