The 1,000-in-May feat was conceived almost by accident. Grace had targeted only the 100th first-class hundred when he opened his 1895 season three weeks late, on 9 May at Hove. By the time he reached the milestone with 288 against Somerset on 17 May he was already on around 450 runs. The press began to chart the May aggregate; he set the target himself in conversation with the Gloucestershire committee on 23 May.
The sequence ran: 13 v Sussex (Hove, 9 May), 103 v Sussex (second innings), 18 v Yorkshire, 25 v Yorkshire, 288 v Somerset (Bristol, 16-18 May), 52 v Middlesex, 257 v Kent (Gravesend, 23-25 May), 73* v Kent, 18 v Middlesex (Lord's), 169 v Middlesex (Lord's, 30 May). The 169 took him to 1,016 by stumps.
The achievement is more remarkable for its context. Grace was 46 (he turned 47 in July), an active medical practitioner running a Bristol surgery, and carrying perhaps eighteen stone. May 1895 was unseasonably cold; tradition holds that the snowflakes settled on his beard during the 288. Across the same month, his Gloucestershire side travelled by rail to Hove, Bradford, Bristol, Lord's, Gravesend and back to Lord's — an itinerary that would tax a modern professional.
