Looks like 2013 was your biggest year. I actually got to 50 races that year (mostly fell) but I don't think I had reached 25 races by May in 2013.
Not sure whether it's possible for me to do 100 as I work Saturdays and have to book holidays around the big races I want to do! I race most Sundays but won't be able to do many doubles.
Haven't done any Parkruns yet this year but my hours might be changing to a 12pm start on Saturdays so I could do a Parkrun before work! Can they be added to my total?
