Sleepy runner's endurance test for charity

The run was also a fundraising bid for the New Zealand Spinal Trust.

A marathon runner is well over halfway in her record breaking bid to run for 500km in 85 hours, with no rest.

Kim Allen has nearly reached 350km since starting running laps of Auckland Domain on Thursday morning.

Her co-manager Mark Gray said Allan was on track to finish the run by tomorrow evening.

Yesterday Allen suffered stomach problems and blisters, but those issues "appeared to be under control now", Mr Gray said.

"She has had blisters that she's put packs on but nothing that's altered her gait."

The run was also a fundraising bid for the New Zealand Spinal Trust.

Allan was once a professional jockey and suffered a severe leg break which indirectly led to her taking up ultra distance running as part of her own rehabilitation.

Earlier she said she was now in a position to do something to raise money for others.

"I'm hoping by doing something really different that people will be inspired to donate to a great cause."

The mother-of-four, from Tuakau, is attempting to break the world record held by US runner Pam Reed who ran 486km in 2005 in just over 80 hours.
