Editor Si and Deputy Editor James saw a month's worth of training come to fruition as they both crossed the finishing line, where they were greeted by little Joseph Kendrick and his family, who set up Joseph's Goal, which has been supported by a host of Premier League footballers and new Everton boss Roberto Martinez.
Joseph is now four years old and has Non-Ketotic Hyperglycinemia, a rare genetic disorder that affects one in 60,000 new-borns. The condition is so serious that less than 500 people in the world are living with it. Joseph's Goal has been set up to raise funds and awareness into NKH.
Any money raised funds research in Colorado, with Joseph's Goal's long-term aim to find a cure to the disorder.
The donations page is still available if you're able to dig deep and make a donation to a great cause.
Joseph's dad Paul - who also ran the race alongside Simon, James and Radio 5Live's George Riley - used to work for TEAMtalk.com and is now football correspondent for the Wigan Evening Post and Wigan Observer.
