Chloe Riley, 21, who is based on the farm section, will swap her keeper uniform for a lemur onesie and trainers for the half marathon challenge around Dudley Zoo's 40-acre site on Tuesday.
She said: "Being a keeper I get to see the impact that Covid-19 has had at the zoo, so I wanted to do something to help as I couldn’t stand by and watch the place I love struggle.
More Covid-19 coverage:
“I wanted to do a half marathon, as I’ve never run this far before, but I wanted to do something that would be a challenge and would be worth donations and those who know the zoo know it isn’t the flattest place, so it certainly won’t be easy.”
Chloe will be running around the site’s current one-way system on her scheduled day off and anticipates it will take her between 10 to 15 laps to achieve the distance.
Zoo director, Derek Grove, added: “We are so grateful for everyone’s support during this unprecedented time for the zoo.
“We are very lucky to have such devoted staff at Dudley Zoo and Castle, who are always keen to go the extra mile for their animals and Chloe is no exception with this adventurous fundraiser.
“We wish her the best of luck and will be cheering her on along the way.”
