But riding 194 miles around the island of Majorca was a more demanding challenge for the novice cyclist.
Alex safely completed the Mallorca 312 – so named to reflect the kilometres covered – within the 14-hour limit.
The tough winding route, climbing mountains and exploring coastal paths, took him near the capital Palma, his home for the last seven years.
Alex hopes to raise £2,500 for St Ann’s Hospice from his adventure in memory of late uncles Ian Haig and Alan Haig who were both patients there.
Last December he also lost his mother-in-law Terresa Provost who was treated by a hospice in Michigan, USA, where she lived.
Alex is engineer and second-in-command on a 30-metre sailing yacht moored in Palma and which will shortly set sail for Turkey and Greece.
St Ann's isn't just a facility. It's a group of compassionate, hard-working individuals who provide genuine love and care. It receives only a third of its funding from the NHS and the rest comes from donations. Cycling is new to me and this was the biggest challenge I've ever done. Palma is a Mecca for large yachts and the owner of my yacht kindly made the biggest single donation to my fundraising. Alex Marsh
