Some of these are from bitter experience, others garnered from those wiser than me. In no particular order
~ Always wear a well-fitting sports bra (these also need replacing during the year)
~ Double knot your trainers (nothing worse than having to stop and retie)
~ Carry a tissue or two (nose frequently ‘drips’)
~ Sunscreen and lip balm whatever the weather
~ Wear comfortable kit
~ Give it your all
Don’t forget that by being outside walking, jogging or running you are lapping anyone sat inside!
