[Case Study] Blister Treatment On The Run
The Adelaide 48-Hour Ultramarathon (2014)
After enduring a scorching bitumen surface for 135km, I had developed 2 x 20c coin-sized blisters under the forefoot of my right foot. Unfortunately Rebecca was not on site at this point (7pm) so my only option was to self manage. After all the various, typical 'blister remedies' suggested by the collective experience on the track, it become such an issue I could not even stand on it, let alone move.
My race was done!
Next morning after throwing in the towel, I was convinced by another runner to go see Rebecca at 8am when she returned. Certain that it wouldn't make any difference, I hobbled my way over to her tent to present my dilemma.
At 8:10am, Rebecca had finished with my foot. I stood, and could noticeably tell the difference immediately. I could walk!
I decided to shuffle around for one lap to test it out. By the back straight I was unable to feel any discomfort in the area and had returned to a full run.
Without Rebecca's treatment, my race was over.
In the final 3.5hrs of the race, I was able to put on another 34km to the tally due the treatment.

Blister treatment on the run
I lanced Matt's blisters with a scalpel blade.
As far as blister treatment is concerned, how you treat a blister depends on the integrity of the blister roof (see image below). So we took these from intact blisters (which means they're sterile) and turned them into torn blisters (which means opening them up to the possibility of infection). This might not always be the best course of action. But I thought it was the best thing to do in Matt's situation and relatively safe due to:
- the blister location
- the amount of blister fluid
- the degree of pain
- the job ahead for Matt's foot
- and the relatively clean conditions
Betadine (antiseptic) was applied and a Primapore island dressing. Both of these are for infection control.
To reduce pressure, I put a felt pad with a cut-out where the blisters were.
And to reduce friction, I put a rectangle ENGO Patch on Matt's insole. Read this to understand what it means to reduce friction for less pain and faster blister healing.
When he passed by the tent on the next lap, he was grinning from ear to ear (which is pretty normal for Matt)!

It's difficult to get people to take blister treatment seriously. So we're starting this article with 6 blister treatment fails that show you why it's important to treat a blister on your foot properly.
Some black toenails are painless, others are extremely painful. Releasing the blood brings instant relief. You can do this quite easily and painlessly by drilling a hole in the nail with a hypodermic needle.
