Scuba Diving During Marathon Training

Hi, 

I have completely messed up and booked a week's scuba diving holiday 3 weeks before my marathon date 

I know i will be tappering my by milage then but would still want to get some treadmill runs in during the week. I was thinking of aiming for three runs during the week, and think perhaps early morning before the days diving would be best. I am also thinking that I should dive with Nitrox all week to keep my nitrogen levels down.  

Does anyone have any experience of diving and running ? Any advice would be greatfully received. Thank you 

Pethidine and Valium would be my drugs of choice in such a difficult situation.

Stick to a depth of 12 feet or less.

Depth and death are linked in this diving game.

I think this is the best thread title I have ever seen on here

I wouldn't imagine diving that far out from race day would make much difference to be honest - 3 weeks would be long enough for any affects to wear off. If you're concerned and if your diving with a computer, just err on the side of caution on allowed combined dive times and depths.

And a few runs on the beach should be a nice change!

Enjoy!

Ideal training to beat this guys record. 

lol, don't think i willl wear the suit Keir!

Thanks for your thoughts Rafiki, I will be diving with a computer so will be extra careful, plus runs on the beach do indeed sound inviting !
