We are challenging all of our employees at Saragossa to exercise the distance between our London and Chicago offices - a total of 6,249 km!!

Run, walk, cycle, swim, row, skip - all forms of exercise will be included and recorded on Strava Group.

The challenge will run from 1 Feb to 30 April.

This challenge is in aid of an extremely important charity - Alzheimer's Association.

Alzheimer's is a national crisis.

Over 6 million Americans are living with Alzheimer's.

One in three seniors dies of Alzheimer's or another dementia.

It kills more than breast cancer and prostate cancer combined.

More than 11 million Americans are providing unpaid care for people living with Alzheimer's and other dementia.

The Alzheimer's Association is the world's leading voluntary health organization in Alzheimer's care, support and research. We need your help to end this devastating disease.
