                        MARTEN TRANSPORT, LTD. ANNOUNCES
                         THIRD QUARTER FINANCIAL RESULTS


MONDOVI,   Wis.,  October  17,  2003/PR  Newswire/  -  Marten  Transport,   Ltd.
(Nasdaq/NMS:MRTN) announced today its financial results for the quarter and nine
months ended September 30, 2003.

For the quarter ended September 30, 2003,  operating revenue increased 14.9%, to
$85.9  million  from $74.7  million for the same  quarter of 2002.  For the nine
months ended September 30, 2003,  operating  revenue  increased 15.1%, to $249.4
million  from  $216.8  million for the same  period of 2002.  Operating  revenue
included  fuel  surcharges of $3.1 million and $11.0 million for the quarter and
nine months  ended  September  30,  2003,  compared  with $1.5  million and $2.9
million for the quarter and nine months ended September 30, 2002. Excluding fuel
surcharge  revenue,  the increase in revenue was 13.1% for the quarter and 11.5%
for the nine months.  The Company measures revenue,  before fuel surcharges,  or
"freight revenue," in addition to operating revenue, because management believes
removing this sometimes  volatile  source of revenue  affords a more  consistent
basis for comparing results of operations from period to period.

For the quarter ended  September 30, 2003, net income  increased  84.3%, to $3.4
million  from $1.9  million  for the same  quarter of 2002.  For the nine months
ended September 30, 2003, net income  increased 55.2%, to $8.4 million from $5.4
million for the same period of 2002.

For the quarter ended September 30, 2003, net income per diluted share increased
53.6%,  to $0.43 from $0.28 for the same quarter of 2002, on a 22.1% increase in
weighted average shares attributable  primarily to the Company's public offering
of common stock  completed  during the 2003 third  quarter.  For the nine months
ended September 30, 2003, net income per diluted share increased 42.2%, to $1.18
from $0.83 for the same period of 2002, on a 8.9%  increase in weighted  average
shares attributable primarily to the stock offering.  Diluted earnings per share
give  retroactive  effect in all periods to the  Company's  three-for-two  stock
split effected in the form of a 50% stock dividend paid on July 24, 2003.

Chairman and President  Randolph L. Marten  stated,  "The third quarter was very
strong for our Company.  Our financial  results improved as a result of stronger
shipping demand,  disciplined freight selection by our operations personnel, and
continued cost control efforts.  Average  operating revenue per tractor per week
increased  6.6% to $2,993  from  $2,809 in the third  quarter  of 2002.  Average
freight revenue per tractor per week increased 4.8% to $2,886 from $2,753 in the
third quarter of 2002. Our operating ratio  (operating  expenses as a percentage
of operating  revenue) improved to 93.1% for the quarter compared with 95.3% for
the same quarter last year. Excluding fuel surcharges from both revenue and fuel
expense,  our  operating  ratio  would have been 92.9 % in the 2003  quarter and
95.2% in the 2002 quarter.

Our  balance  sheet  improved as well.  During the quarter we  completed a stock
offering  that  resulted in net proceeds to the Company of  approximately  $52.1
million and raised our stockholders' equity to $140.4 million. At the end of the
quarter we had  approximately  $31


million of cash and $31 million of  long-term  debt,  making our  balance  sheet
essentially debt-free on a net basis."
