The first bicycle race at the Park was on Friday July 22nd 1870 at the annual fete of the Oswestry Institute**, where the entertainments included archery, croquet, skittles, Aunt Sally, marionettes, singing and dancing. There were also three running races and two bicycle races, the one mile bicycle race, needed two heats and was won by Isaac Jackson of Wrexham, his prize was £2, Jackson also won the half mile bicycle race rather easily. Music was provided by the Oswestry Volunteers and the Denbigh Militia, there was dancing into the evening and a display of fireworks. It was estimated that there were 10,000 people on the ground, many arriving by special trains, admission was one shilling. The shops in Oswestry were closed from noon on the day of the fete.
For the next thirty years, fetes were held at the Park at least once and sometimes several times each year, the owners of Wynnstay Hall often invited the Oddfellows or the Forresters to hold fetes. The following organisations also had fetes and sports in the grounds; Wrexham Working Men's Club, the Good Templars, Oswestry Institute, the Druids, Ruabon and Rhos Flower Show. When bicycle sports were included, it was usually one and two miles bicycle handicap races.
The Oddfellow's held their fete on Whit Monday 1899, which started with a parade through the streets of Ruabon, headed by Rhos Silver Prize Band. The sports consisted of three running races and two bicycle handicap races over one and two miles. Tom Kinsey of Chester won the one mile race, his prize was a marble clock, value three guineas and S Clutton of Marchwiel took the two miles and won a set of cutlery, value four guineas. Entertainment between heats was provided by the brothers Lindon on the triple bars, the brothers Carteno on the double trapeze and "the aerial wonder Astella on the high wire." There was dancing in the evening led by the Rhos band.
By 1900 the Foresters and the Oddfellows were holding their Whit Monday sports on alternate years, the fetes were very popular, in 1912 there were over 5,000 spectators. There was often an additional fete in September for the Ruabon Flower Show. These fetes always included bicycle races, which were always one and two miles bicycle handicap events.
Fetes and sports at the Park stopped for the First World War, but the was one more meeting after the war. This was the Wynnstay fete on August 3rd 1920 promoted by the Ruabon Friendly Societies, which included two bicycle handicap races over half and one mile. This was the last bicycle racing at Wynnstay Park.
The house still exists, it was a private college until 1994 and then it was sold for flats and houses.
** The objective of the Oswestry Institute was the moral and intellectual improvement of their townsmen. They were raising funds to build a new public library for Oswestry.
