Off Road First Aid Kit

some races require a mandatory first aid kit with a specified contents list, but to be honest if its something that can be fixed by a first aid kit you can probably get by with out fixing it and if it needs more than first aid then the kits not much use anyway. But in saying that some vaseline and zinc oxide tape go a long way. The other thing I've used more than anything else are indegestion tablets.

but a basic kit is a good idea, i suppose.

a survival bag,whistle,warm top,hat,mars bar and waterproof jacket will cover you for most things.   

Carry a safety pin for inscising blisters (if you do not already have four attaching your race number). 

I carry a smal roll of duct tape for repairing blisters and other broken body parts.  It is waterproof and can be torn to size with bare fingers. 

Painkillers can take the edge off minor injuries and you feel more confident knowing that you can fall back on them if you have to.  A tube of ibuleave gel is easy to carry and aply, and can be used to treat soft tissue injuries.  Biofreeze is effective but hard to get hold of. 

Hi

 I would certainly recommend blister plasters as a starting point and the all important small pot of vasaline for those all too chaffed areas that happen to the very best of us!!  Better to use your own pot rather than delve in to a pot being held out by a first aider or race official!  Imagine how many fingers have already been in that pot!!!!  If you want any further first aid advice, have a quick look at my site and drop me a line.  http://www.firesafety.org.uk/first-aid-training.php 

And if all else fails, if it hurts that much - STOP!
