I ran a pb in a 10 kms race in Eynsham on Sunday. So what? Nice sunny day, lovely flat course, very well organised. What was odd was that I'd had a hard training week with over 60 miles on the bike and about 25-30 running, with 2 swim sessions. I arrived late ; no time for a warm up ; I should not have run quickly (for me that is) but half way round I had a really strong mental image of what I would look and feel like while I was running the second half of the race. It would look smooth, feel strong and relaxed etc and blow me if that wasn't exactly what happened. Instead of blowing up I ran the second half faster, with good form and haven't really come down yet.
I tried it again on my recovery ride yesterday and a similar thing happened. It's hard to be sure if the brain drove the physical performance, or just unlocked the potential. Anyone experienced anything similar?
