It is this simple:-

1. Pay a £5 registration fee at www.justgiving.com/PACT2016 or simply text PACT57 £5 to 70070. It's easier for us if you tick gift aid and tell us who you are in the message!

2. Exercise everyday in 2016 and pay a £1 charity fine for each day you miss (up to a maximum monthly fine of £10). Pay on the above link in a monthly lump sum or text PACT57 £1 to 70070.

3. Rope in as many of your mates, colleagues, clubmates, family to join the challenge.

4. Log your exercise miles from 1st Jan 2016 (details of how will be confirmed before 1st).

All donations go straight to Birmingham Children's Hospital via Justgiving. Justgiving take a nominal percentage of online donations for providing their services however if you donate by text the full amount goes to the charity. This challenge is based on your circumstances and is judged by your honesty. It is your challenge!
