Denise completed the 5km race in Bedford, running, crawling and sliding through a wet and muddy obstacle course consisting of cargo nets, pipes, and some inflatable fun!
Afterwards Denise said; "It was great fun and for a brilliant charity cause, I can't wait until the next one!!"
You can help Denise raise money for this great cause by donating directly to her fundraising page:

JustGiving sends your donation straight to Cancer Research UK and automatically reclaims Gift Aid if you are a UK taxpayer, so your donation is worth even more!
