Ive been doing 13 miles each way since May
and loving it mostly B roads not much traffic
,the joys of living in the country mostly do 5
days a week takes 50 mins there an hour
on the way back..bloody hills,
still manage night rides and weekends on the Mtb
with no I’ll effects I feel it’s really improved my stamina
and overall fitness to be honest it’s the highlight of my day
I arrive at work (7am start) invigorated and raring to go
and the cycle home gets rid of any
work related stress, I could possibly do an extra couple of miles
each way but not much more I think around 15-16 miles each
way would be my limit
