Today all of my wildest dreams came true. After graduating from C25K in April, today at Parkrun, I ran sub 30 for the first time ever! I've been getting PB's over the last few weeks. Last week was 30.44 and today's was 29.44. Thanks to a pacer whose job it was to run 30 minutes. She actually apologised after for running too fast! What you may feel to be impossible is not impossible at all! Just go for it.
