Runners sprint down Massachusetts Street in the first Irish Mile, held on St. Patrick’s Day 2017. The event will return this year.

Spring seems to be upon us, bringing with it plenty of runs, races, 5Ks, jogs and more.

One fun highlight this month is an opportunity to run like somebody’s after your Lucky Charms — and it comes with a chance to find a pot of gold.

The second annual Irish Mile will send runners from 11th and Massachusetts streets down to Seventh and back for a 1-mile race. In order to draw top talent, the race has a $2,000 prize purse, and this year has added a costume competition with a $50 gift certificate grand prize.

J. Jenkins, co-owner of Ad Astra Running, which organizes the race, said he expects participants to double from 76 last year to roughly 150 this year.

Registration is $33 until March 11, when it increases to $40. It’s a fundraiser for the same charities the St. Patrick’s Day Parade benefits — this year, Baby Jay’s Legacy of Hope, Cooper’s Cause Foundation and O’Connell Youth Ranch.

Mike Ostrekko, Lawrence, competes in the Ad Astra Irish Mile race through downtown on Friday afternoon, March 17, 2017.

Paradegoers, beware — the race starts at 12:30 p.m. and ends by 12:45, so the street can be cleared quickly in time for the 1 p.m. event. Jenkins said police hope people are aware of that and try to arrive earlier to alleviate last-minute traffic.

Here’s a list of a bunch of major runs in the area through the spring and summer. More information on some events will become available as they get closer.
