IMH - questions about special needs

1> How many miles into the bike is it?
2> It’s around mile 18 of the run, right?
3> For bike special needs - do they really enforce the food only rule - or is sticking an extra tubular + CO2 okay?

Special needs on bike is in Hawi near turn-around. I put a spare tubular with co2 in it, no problem.
Special needs on run is at bottom of Energy Lab which puts it between 17-18 miles.
