I have a record of every fell race i've done... date/time/position.... all recorded in the back of the FRA calendar for that year. Then a separate list of how many times i've done each race and my pb time/position.
Currently stand on 103 races, of which exactly 50 have been long/ultra distance.
Used to collect the numbers but just became too many... also when you take off your muddy, sweaty vest, then get home several hours later and try to retrieve the number off the front, it's often in a bit of a mess.
