Irene Evison will be donning her outdoor footwear in preparation for a cycling challenge to encourage people to visit national parks.
As a trustee of the Campaign for National Parks, she has challenged herself to cycle at least 120 km in each of the three Welsh National Parks.
Her trip will encompass Snowdonia, the Brecon Beacons and the Pembrokeshire Coast as she hopes to raise money and awareness.
The cycle will commemorate the 75th anniversary of the Campaign for National Parks and will contain stop-offs to find out why people find the parks so important.
Ms Evison claimed that the trip was not simply about having fun but also about understanding nature and its benefits.
Norma Barry, head of Welsh affairs for the Campaign for National Parks, said: "Our organisation campaigns tirelessly to protect Welsh national parks from inappropriate developments and keep them safe for future generations so they too can benefit from them."
