Daily, 30 miles. I'm a police cycle trainer, so probably nearer 45 if I'm training that day.
200-250 miles a week. Deliberately try and have a day with no riding every 8 or 9 days to alloy my creaking joints to rest
Cadence - I've never measured, but I suspect around 95 rpm.
Work based cycling - 18 mile round trip minimum, 6 mile on top of that if traffic is gnarly and I fancy a quieter route.
Qualifications - MIAS level 4B Emergency Services MTB patrol skills instructor, road skills, off road skills, defensive tactics, search and rescue, basic maintenance, first aid. Member of IPMBA. Due to be assessed next month for my L5 ticket so I can then train others to Instructor level.
As for the CO2, I'm a big, heavy, wobbly jelly, so could we say 500g per km?
